Physical change - a change in a substance that does not involve a change in the identity, including a change in state between solid, liquid and gas phases.
Chemical change - a change which one or more substances are converted into different substances, some indications are burning, rusting, color changes etc.
physical change can be changed
but in chemical change chemicals are mixed together
for example if we are sick that is a physical change

A physical change is when the object undergoes a change that can be reversed, such as mixing water with salt, melting ice, or freezing or vaporizing water. A chemical change is a change that changes a substance into something else entirely, and therefore cannot be reversed. Examples would be mixing vinegar and baking soda or turning batter into bread.
chemical change is when during a chemical reaction a new substance will be formed while in physical change no new substances are formed
