What is physical change?
Answers
Answer:
A physical change is a change to a sample of matter in which some properties of the material change, but the identity of the matter does not. Physical changes can further be classified as reversible or irreversible. The melted ice cube may be refrozen, so melting is a reversible physical change.

Solution :-
⠀⠀⠀⠀⠀⠀⠀A physical change can be described as a chnage in which no or less or negligible properties of a given sample is changed. Here, the chemical composition of the given sample remains unchanged.
⠀⠀⠀⠀⠀⠀⠀In a physical change, no new substance is formed. Only the shape, size changes. These changes are generally irreversible in nature. These changes does affect the physical properties of a sample, but no significant change in chemical composition can be observed in it. These changes are mostly temporary and after a short time, they turn back to normal.
⠀⠀⠀⠀⠀⠀⠀Some examples are, breaking of glass, melting ice cube, crushing a can, shredding paper, etc.

Extra Information :-
- Ques )= What is a chemical change?
- Ans )= A chemical change is contrary to physical change. It is permanent in nature. Chemical composition of the given sample does change after the chemical change. Not only this, but the physical appearance might also change.
