Question

When vapour phase condenses then choose the correct option and also give correct reason
a) the surrounding air may become warm or cool
b) the surrounding air becomes cool
c) the surrounding air becomes warm
d) any of these

Answer 1

c) the surrounding air becomes warm    due to release energy by the vapours..

Answer 2

When water vapor condenses onto a surface, a net warming occurs on that surface. The water molecule brings heat energy with it. In turn, the temperature of the atmosphere drops slightly. In the atmosphere, condensation produces clouds, fog and precipitation (usually only when facilitated by cloud condensation nuclei).
