Question

Formation of snow is physical change. Explain

Answer 1

it is a physical change as snow can be converted to water again.

Answer 2

Answer: Physical change is a change in which there is no rearrangement of atoms and thus no new substance is formed. There is only change in physical state of the substance.

Formation of snow is freezing of water, thus liquid changes to solid state.

$H_2O(l)\rightarrow H_2O(s)$

Chemical change is a change in which there is rearrangement of atoms and thus new substance is formed. There may or may not be a change in physical state.
