I just found it in my Chemistry Textbook, it's a GCSE one. So they do expand more.

First, ask yourself if gases do expand more than solids for the same increase in temperature. Do they?
Well, a gas at ANY temperature will continue expanding until it reaches the wall of a container (or can't escape from a gravity well, in the case of the atmosphere).
However, a gas inside a movable piston will push the piston up a significant amount when it is heated. The reason for this is that while the molecules in a solid are tightly bound together, gas molecules are not bound to each other at all. Increasing the temperature increases the speed of the molecules, meaning more collisions with the walls per second. A faster collision rate means increased pressure on the walls.

They don't. It's relative to pressure as well as chemical composition.
