(5) Separation of gases from air​

Answer 1

Answer:

Composition and properties of fruit initially are entirely different than those after ripening of fruit. It cannot be reversed. Hence, it is a chemical change. (ii) Crystallization of a substance is a physical change because there is no change in composition and chemical properties of the substance.

Answer 2

Answer:

1) chemical change

2) physical change

3)phycial change

4) chemical change

5) physical change

Explanation:

1) cause it's irreversible

2)it's reversible

3) this is also reversible process

4) it's irreversible cause the there is loss of energy and change in chemical composition

5) it's reversible

hope it will help u ^^
