Why does gas expaned more than liquid or solids?

Answer 1

Here's my interpretation.

A gas is at a higher energy state than a solid for any given material. This means that the gas has overcome some sort of restriction inherent in the solid state; namely, the gas molecules are less strongly attracted to each other than the solid molecules. So, any energy put into the gas will result in more motion than in the solid, as less is wasted to overcome the intermolecular forces. Think of kicking a pile of sand, and then kicking a block of concrete. The sand will move more :)

Answer 2

Gases expand more than a liquid because the molecules present in liquid are lossely packed , so it molecules ca move freely .

I would like to add a little more to that answer:

Gas molecules have an indefinite volume and an indefinite shape while a liquid has an indefinite shape but a definite volume. Volume is the amount of space an object takes up. So gas expands more than liquids because it does not have a form. It can expand anywhere.

Answer 3

Because the molecules are more free to move therefore when even small amount of heat is supplied to the gas it's molecules are able to move faster and increase in pressure will occur which leads to faster expansion

Answer 4

Because there is more space for heat on between atoms in a gas, whereas there is almost no space between atoms in a solid.

Answer 5

because the molecules of the gas is lesser than the solid and liquids and it has enough space for them to expand..

Answer 6

The intermolecular forces are not strong.
