Answer 2

Answer: False

Step-by-step explanation: Physical change is a change in which there is no rearrangement of atoms and hence there is no production of new substances.

`H_2O(l)\righatleftharpoons H_2O(g)`

This is a physical change in which water only changes its state from liquid to gas.

Chemical change is a change in which there is rearrangement of atoms and hence there is production of new substances.

`2Na+Cl_2\rightarrow 2NaCl`

This is a chemical change in which sodium combines with chlorine to form new substance sodium chloride.
