Question

Consider the expansion and contraction among solids, liquids and gases, the one which has a greater tendency to expand is :

• A. solid
• B. liquid
• C. gas
• D. none of these

Answer 1

The correct option is C gas

Gases have a greater tendency to expand because it has no or negligible intermolecular force of attraction between the particles.

Hence, they can move easily, resulting in expansion whereas solid has a compact structure, they have the least tendency to expand.

Hence the correct option is C.
