Answer:
B) evaporation
Explanation:
Evaporation -
It the process of conversion of liquid state to gaseous state , is known as the process of evaporation .
Condensation -
It the process of conversion of gaseous state to liquid state , is known as the process of condensation .
The state of equilibrium is the one , where the process of condensation equalizes the process of evaporation , and there generates a state of physical balance , i.e. , both the forces balances each other .
