In the atmosphere water vapor condenses to form clouds.
a. true
b. false

This statement is  that says water vapor condenses to form clouds.

Further Explanation:

The phase change is defined as the change from one state to another state without altering its chemical composition. It is also known as a phase transition, state change or physical change. The two phase changes that occur during the formation of clouds are condensation and evaporation/vaporization.

Condensation: It is the phase transition that results in the conversion of vapor-state to the liquid-state.

Evaporation: It is the phase transition that converts the liquid into vapors. This process is also known as the boiling of liquid. In order to change the liquid state to the vapor state, the temperature is to be increased or heating is done.

Cloud formation:

Due to the heating of the surfaces, air becomes warm and it rises. The temperature in the upper atmosphere is less so air becomes cool. The relative humidity of air rises. At a point, it becomes saturated. This heated surface results in the evaporation of water to form water vapors. As these are lighter than air, they rise up and reach the upper part of the atmosphere. The temperature in the upper region of the atmosphere is very less and therefore large number of tiny droplets of water vapors condense to form clouds. So the given statement is true.
