A physical change is a change of a substance from one form to another without changing its composition.

Part B:

A physical change is a change of a substance from one form to another without changing its composition. Example: A balloon deflating into its original form.

A chemical change occurs, one substance combines with another substance to make something completely new. Example: Making and baking a cake.

Answer 2

A/a physical change is when an object goes through a natural change such as weather etc.
B/ the different is that 1) chemical change is more quick to change rather than physical (ex: I’d there is rocks flying around and is wearing down another rock it would take longer rather than acid)
