Q. During the evaporation of liquid
A) The temperature of the liquid will rise
B) The temperature of the liquid will fall
C) May rise or fall depending on the nature
D) The temperature remains unaffected
Explanation
(b)
During evaporation, molecule having high energy leave the surface of liquid. As a result average kinetic energy of liquid decreases.
$\because KE \propto T$
$\therefore$ Temperature of liquid falls.
