GEOLOGY

Detailed explanation-1: -A change in which a substance undergoes a change in its physical properties is called a physical change. A physical change is generally reversible. In such a change no new substance is formed.

Detailed explanation-2: -Chemical Change. Chemical changes occur when bonds are broken and/or formed between molecules or atoms. This means that one substance with a certain set of properties (such as melting point, color, taste, etc) is turned into a different substance with different properties.

Detailed explanation-3: -Matter can exist as a solid, liquid, or gas (or plasma) and can change in many ways. Physical changes are those in which the shape, size, or state of the matter changes, but the substance is still essentially the same. For example, chopping up a carrot or ice melting into water are both physical changes.

Detailed explanation-4: -The decay of matter is not a physical change.

Detailed explanation-5: -In a physical change, form of matter is changed from one form to another but no new substance is formed. Physical changes can be reversible in case of water and it’s forms whereas in case of cutting a paper/fruit/tree, the change is neither reversible nor temporary.
