A physical change in matter is when the shape of something changes. A chemical change in matter is something rotten.

A physical change doesn't form new matter, it only changes the look.On the other hand a chemical change is when to chemicals get together and form new matter like a gas. It sometimes changes the look of something but it goes through a chemical reaction first.

A physical change is when something changes, it may look or feel different. Like a piece of cake if you cut it into a slice it will still be the same. A chemical change is when something does not stay the same and will change. Like if you mix baking soda and vinegar together it will explode!

Physical changes are something when you break it or do something to it is still the same thing. For example if you break a stick in half it is still a stick.

A physical change is when your only changing the look of it. A chemical change is when you actually change the molecules in the solid, liquid, or gas.

A physical change is when you change the shape of something but it is still the same type of matter. A chemical change is when you change the type of matter, for example, changing a solid to a liquid.

A pysical change is when matter's look changes but not the whole thing. A chemical change is when the chemicals change.

A physical change is reversible: an example is water to ice and ice back to water. A chemical changes are not reversible: like frying an egg, you cannot change it back into a raw egg.

A physical change is when something changes to another thing but still the same thing. A chemical change is when a boat rusts or when a egg rots.

A physical change is when something changes to some thing but still is the same thing. A chemical change is when something turns to rust or rots.

A physical change is when something is the same material but turned into a different thing. A chemical change is when 2 things combine together as a mixture with chemicals to form another type of matter.

The difference between a physical change and a chemical change is physical is something that only changes it's shape and size . Example if there was a box of crackers and you open the box and the crackers are mashed that is a physical change. A chemical change is when two substances come together and mix. Sometimes a chemical change can make an explosion like mixing vinegar and baking soda.

A physical change is when something changes it's shape or size it but it's still the same. A chemical change is when two chemicals are mixed together to make a new chemical.

Chemical changes occur when a substance is combine with another to and from a new substance called synthesis or alternatively decomposes 2 or more different substances. Physical changes affect the form of a chemical substance, but not it's chemical composition.

A Phsical change does not do much to the matter like broken glass, it's

A physical change can be noted by sight or touch, like a change in shape. A chemical change is when one or more chemical substance can manipulate one another and causes a a change in matter.

A chemical change is when something is added to whatever you have. A physical change is when the shape of something is changed.

A physical change changes the shape and size like a broken pencil.
