Why can a physical change be easily reversed?
it can be easily reversed because nothing new is produced. it is the same particles but just rearranged. it is just a change in size, shape or state ***IT IS REVERSIBLE*** but what physical change is not easy to reverse?

What is physical change in matter?

What changes of matter occur in respiration?
A change is said to be physical if no new substances are formed. Physical changes are temporary and can easily be reversed to give back the substances in their previous form. Freezing of water is an example of a physical change. A change is said to be chemical if new substances with different properties are formed. Chemical changes are permanent and cannot be reversed to give back the substances in their previous form. Burning of paper is an example of a chemical change.
Why physical change can easily be reversed but chemical change cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
