Answer 2

Answer:

The correct statement about physical change is that it does not change the material composition.

What is a physical change?

• a Physical change is one that leads to changes in the states of matter and energy.
• as the name suggests, the size, form, and color may all change in the matter when it undergoes a physical change.
• A substance may change shape or form while undergoing a physical change, but no chemical reactions occur, and therefore, no new compounds are produced.
• Many physical changes can be undone if enough energy is supplied.
• Combining items results in physical changes but no chemical reactions.
• boiling and freezing, cutting, cooking, etc. are all examples of physical changes.

hence, a physical change does not change the material composition but all the other statements stand incorrect in terms of a physical change.
