Which of the following processes must exist in equilibrium with the condensation process when a measurement of vapor pressure is made?

a) fusion

b) evaporation

c) sublimation

d) boiling

e) none of these

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 .
