Which of the following three states of matter have (has) forces of repulsion that are far greater than their forces of attraction?
a) Solids b) Liquids c) Gases
a, b, and c
a and b
a and c
c
b and c
Homework Answers
Solution:
The correct option will be C (gases).
The gas molecules are held togather by very weak Vander waal force of attractions. In case of real gases, the force of repulsion is higher than the attractive forces.
It is measured by compressibility factor(Z).
Z = PV / nRT
If Z > 1, then repulsive force dominates over attractive force.
