Physical changes are something that you can do like pell a orange 🍊. And you can also cut something ✂️. You can fold something to📁.and it can be done by its self.a chemical change is different because.it is when a tool that can heat something up does it .like a oven or stove . Or a microwave grill frying something and so much more.this is all for now bye😎

The two are different because physical change is were you could cut or fold something to make it change but on the other hand chemical change is were something would rot or mold.For example,you could fold paper or cut it.When a chemical change happens you could find mold on food or you could find rotting on bark.So a physical change is basically something you can do to something and a chemical change could be were nature or any other stuff could cause something to happen.

Chemical and Physical are different because a Physical change is like cutting or folding paper and a Chemical change is like cooking something or peeling an orange. That is why the two is different they are both changing something but changing it in a diiferent way like peeling and orange and cutting paper. that is all I have to talk about today seeya

So physical and chemical change or like physical is biting into an apple chemical is when the apple turns brown in a while so physical and chemical change or when something changes and item or anything another physical and chemical change or a banana after a while or a banana will rot or you can peel the bananas

Physical is change is when a person does something to and object. For example folding paper or riping paper into pieces. Chemical change is when something changes without human control to where nature changes the object. For example a pumpkin rotting in the sun is a chemical change.

The difference between a chemical and physical change is a pysical change can be fixed for example if you rip a piece of paper you can just tape it back.But if you are talking about a chemical change you cannot tape it back it is not possible for example you burn a peice of paper its gone its black and there is no way of fixing it.Thats all from Brantley the Rhino Byeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

The difference between physical and chemical changes. A physical change is when the size, shape, or state of an object is changed. For example, you could take a piece of paper and cut it it and also fold it that is an example of a physical change. But the paper is still paper it may look different but still paper. A Chemical change is when a object reacts with something else. Chemical changes include smell color and heat. A new substance appears. And that is The difference between physical and chemical changes. :)

This is what chemical and physical changes or a chemical change is say burning something or when something gets destroyed. A physical change is whenever something just changes in its shape or size.

The difference between the two types of reactions physical and chemical reactions are physicall is you are not creating a new substance but chemical reactions you are creating a new substance.For a physical example I'll do an experiment.You will need to get a fruit of any sort and a knife.First/ next/ last cut the fruit.And ........TADA ! A perfect example of a physical reaction. Now I will demonstrate the chemical reaction.Of course I am going to use a experiment.You will need to get a recipe of something to cook. You can ether burn that or do my experiment your choice.Then make the batter.Last cook the batter.And boom!A chemical reaction.That wraps up my b-o-l-g!

the difference between physical and chemical changes are physical changes you can put back. and chemical changes you cannot. for example ripping a paper, moving something, or even peeling an orange. an example for chemical changes are cooking something, melting something, or burning something. that's all for today byeeeee.

A example of a physical change is cutting paper. The look is the only this that changes. A example of a chemical change is paper that was burned. You can't unburn it and it's changing more than it's look. The are more examples like this molding and rotting for chemical. For physical changes you can cut or move it but the look or appearance is the only thing that changes.

The difference is that physical changes can be turn back into what it originally was and that it’s the same thing still. Some examples are like folding a piece of paper, tying a price of rope into a knot, or peeling the skin off of a banana. Chemical changes are things that make new substance or can’t go back into its original thing like burning a piece of paper, a piece of iron rusting, or some fruit rotting. So the main difference is that one is still the same thing a one is now a new thing.

Physical and chemical change are very different let’s talk about physical change first physical change can be reversible like when ice melts and you can freeze it again by putting it into the freezer.Now let’s talk about Chemical change!Chemical change is where once you did something you can’t go back for some examples metal rusting,a cake cooking in a oven , and wilting flowers we don’t have a reverse 🔄 button where you can stop it from doing something that’s why we have something called ✨chemical change✨ And if we did chemical change wouldn’t exist.

The difference between them is that one is reversible and one cant be reversed like the examples in my comment and if they switched that would be just weird because we normally don’t see something LIKE THAT everyday. 👋🏼

Physical and Chemical changes are very different. physical changes you Some what have what you started with Let's say you ripped a shirt You can stitch it back together and it's good as new Because physical changes can be changed back into what they want for sometimes.Now chemical changes on the other hand are somewhat different Because If you have what saying orange and you leave it out it will get moldy and that's a chemical change unlike a physical change a chemical change is permanent so a moldy orange is Permanent.

The difference between physical and chemical is physical changes the way it looks like if I was getting a piece of paper and ripped it it was a physical change. A chemical change is when a pizza is cooking in a oven and it inflates or smells different.

There are many differences between physical and chemical changes. One difference between physical and chemical changes is that physical changes change the shape of the object but chemical changes do not change the shape of something. Another thing is that chemical changes are natural while physical changes are not like a chemical change is rusting. These where two reasons chemical and physical changes are different.

The difference between chemical cadges and physical changes is that chemical change you cannot fix it or put it back together. On the other hand, a physical change is when you can put something back together again. For example take this character from a story: Humpty Dumpty, he is an egg, so if I were to break his shell that would be a physical change. But if I cooked him that would be a physical change because I couldn't undo that. That is the difference between a physical change and a chemical change.

A physical and an chemical are different because a chemical is when something if you leave something out like a fruit 🍎 it will smell bad or will like muddy or something like that and a physical is something like ice 🧊 melting or a glass breaking . (And this is not all of them but this what I got )

Hello! Physical is one way of doing something to an object or food. For example, cutting a apple that is a way of physical change because it changes it physically. Now chemical change, that is where a chemical is involved. For example, a banana turning black and brown that is a chemical reaction called rotting. Those are what chemical and physical changes are and some examples of them.

The difference between physical change and chemical change is that Physical change is when you can put stuff back together let’s say like ripping a piece of paper you can put it back together by using take or something. A chemical change is when you can not put it back together for an example you can’t put back together a fish tank because it broke and you have to by another one.

Physical and chemical property are different because physical activity s rust rotting car crash before and after basically it is just what you see like my desk it has scratch’s and it is messy and now chemical like when pools are dirty they have chemicals that that you put in it then you come back the next day and it is blue like my moms car was silver and now the rims are black and paint is a chemical so it is a chemical and physical change when you use chemicals like my mom does to bleach shirts she uses bleach to make them different colors and she also puts drops 💧 of paint in the bleach to make it a different color that is all I know about physical and chemical differences byeeeeee

A chemical change is occur when a substance combines with another substance to make a new substance. Like if a pumpkin rots it turns into something different. Or when you fry a hotdog. And when you are rusting an iron pan or cooking an egg. All of those things are chemical changes.

Chemical and physical changes are different because physical changes are things that you can reverse chemical changes are not able to be reversed an example of a physical change is like you can fold paper you can also unfold it and get it back to Normal a chemical change is something you cannot reverse an example of that is bread if you toast the bread you cannot untoast it it will not go back to regular bread so after you toast it you can’t get it back.

One example is a bar of chocolate,if you leave it out for to long in the sun then it will melt that is a chemical change and one physical change is when you break the bar in half or maybe if you drop it it will shatter that is a nother physical change.

A physical change is when something stays the same like if you fill a balloon 🎈 with water and pop it, it is still a balloon 🎈. A chemical change is when something burns or gets rust on it. For example putting bread 🍞 in the toaster it burns or heats up.

A physical change occurs when the size ,shape, or states of an object is changed. Cutting and folding paper are some examples of physical changes . And when you put a peace of string into water it is still string it is just falling apart in the water you put it in. In a chemical change an object reacts with something else. A new substance is form.

The difference between physical and chemical change. In example of a physical change is a piece of paper and you fold it in half it's still the same piece of paper if you can change it back it is a physical change. But a chemical change, on the other hand, you can't change it back like if you make a cake you can't change it back to cake batter or eegs. So the difference between physical and chemical change is one you can change back and the other you can't.

The difference between a physical change and a chemical change is that a physical change it that if you peel an orange 🍊, it stays the same like it is still an orange because all you take out is the peel and no new substance is made which is a physical change. And a chemical change is that when a banana 🍌 is stirring lonely outside in the sun it rots and becomes all mushy and stuff. And it also is a fruit that ripens and it’s texture changes and color like black or brown like brownies.

Physical and chemical changes are different because a physical change is when you can be cutting an orange. But a chemical change is when an orange rots and starts to get moldy. but those are not the only thing that they can be cars, boats, and even wood. cars have metal and if you haven't seen a rusted car well that's sad because that rust is actually a chemical change. But if its a boat it can be in the same way because boats also have a lot of metal. The last thing is wood wood can rot like the orange but then physical change is that wood can be cut to make paper. Those are the reasons of chemical and physical changes.

A physical change is when you change some things but it’s still the same item or you can put it back in the same position. Like if I blow up a balloon That would be a physical change because it’s still a balloon and I can pop it in it’ll turn back. Or if I fold a piece of paper it would be A physical change because I can unfold it so it’ll turn back normal and it’s still a piece of paper. A chemical change is when a chemical change something. For example if a I cooked an egg it would be a chemical change or if I burnt a piece of paper it would be a chemical change because it is no longer paper it is ashes and the chemicals in the fire change the paper. That is what Chemical change and physical changes are

The difference between physical and chemical changes are that a physical change is when say A piece of paper is folded but it’s still the whole piece of paper. A chemical change is when you take something and do something to it to make it a new substance. It changes color, smell, and heat. For example a apple can rot and turn brown and be mushy and smell bad. Another example of a physical change is a balloon. When it it pops it’s till the balloon but in tiny pieces. If could be put back together you would use the pieces to fix it. Another example of chemical change a sandwich. A sandwich can sit out and get moldy. It will turn black, and start to smell. This explains the difference between physical and chemical changes.

A physical change is when you do something to change the appearance of a object for example, a physical change is if I count a piece of paper in half. A chemical change is when change what something looks like and you can not undo it for example, a chemical change is if I cook a piece of steak I can not uncook it. The difference is that a physical change just changes the appearance and a chemical change changes something and you can not just undo it BYEE.

Pysical and chemical change are different because pyscial change is when you cut something like a orange or apple a chemical change is like when something rotten like a apple plum or a banana and starts to get moldy but there are more things that you can cut like a cake and there are more stuff that rotten.

The difference between physical and chemical change is that physical change is doing something physically like tearing a paper. Chemical change is when something happens naturally or you like light a match which is a chemical change because it heats up.

The difference between chemical and physical change is for chemical it will be used with a substance and for physical is will be used for changing shape and volume. An example of a chemical change is a car rusting from being exposed to water for a long time. An example of a physical change is folding a sheet of paper into a paper plane.
