Chapter 14, Problem 8A

Interpretation Introduction

Interpretation:

The change in the boiling points of the noble gas elements is to be explained.

Concept introduction:

The temperature at which the vapour pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapour is called as boiling point.

Answer to Problem 8A

For noble gases, the boiling points increases with their atomic masses.

Explanation of Solution

  

The graph shows that as the atomic number increases there is an increase in the boiling point.

For noble gases, the boiling points are very low because only weak London dispersion forces are present.
