Interpretation: The reason for the increase in evaporation on increasing temperature is to be explained.
Concept introduction:
A liquid is a nearly incompressible fluid and has the shape of its container and maintains a (almost) constant volume under all conditions of pressure. The volume is fixed if the temperature and pressure are both constant.
Answer to Problem 44A
The average kinetic energy of liquid particles increases.
Explanation of Solution
The average kinetic energy of a liquid's particles rises as it warms. As more and more molecules can reach the liquid's surface and enter the vapor phase, the rate of evaporation accelerates. The liquid eventually reaches a point where all the molecules have sufficient kinetic energy to evaporate.
