Question

why do gases expand more than liquids?

Answer 1

Answer:

The atoms themselves do not expand, but the volume they take up does. ... Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.

Answer 2

Answer:

Because the inter molecular fore of attraction between the atoms of gasses is less as compared to liquid ,therefore gasses expand more than liquids
