Chapter 7.11, Problem 6QQ

Interpretation Introduction

Interpretation:

Among the given options, the correct one for what effect will decreasing the temperature of a liquid by $15°C$ have on the rate at which the liquid evaporates has to be chosen.

Concept Introduction:

Evaporation is a process in which the molecules escapes from the liquid phase to the gas phase.  According to Kinetic molecular theory an evaporation can be explained as, not all the molecules present in a liquid or solid or gas possess the same the same kinetic energy and at any instant, some of the molecules may have above average kinetic energies and other may have below average kinetic energies as a result of collision between molecules. The molecules overcome attractive forces with other molecules.  The liquid evaporates depends on the rate of the process.
