Chapter 11, Problem 76QP

Interpretation Introduction

Interpretation:

The dependence of intermolecular forces in a liquid on its critical temperature and boiling pointand the reason for greater critical temperature of water are to be explained.

Concept introduction:

The temperature of a liquid,at which its vapor pressure becomes equal to the external atmospheric pressure, is called itsboiling point. At this point, liquid and vapor are in equilibrium. The liquid is converted to vapor beyond this point.

The temperature, beyond which substances cannot be liquefied with ease, is known as critical temperature of that substance.
