The correct option is A Converting gaseous molecule from gaseous state to liquid state.
The
phenomenon by which gaseous molecules convert from gaseous state to liquid
state is called condensation. It is the process by which water vapor in the air
is changed into liquid water. Condensation is responsible for the formation of
clouds. That’s why it is crucial to the water cycle. These clouds produce
precipitation which is the primary route for water to return to the Earth’s
surface through rain. Condensation is the opposite of evaporation.
