Because of diffusion. (molecules move from an area of high concentration to low concentration)
Being made up of infra red rays which will move in all directions and refract when hitting paticles heat will always expand
It will contract.

The gas expand to fill the volume of the container.
Because a gas will expand to fill the other half. Gas has no defined volume. Liquids do.
In a free space gases expand.
Applying heat to a gas will make it expand. If the volume of the gas is restricted (i.e. it cannot expand) then the pressure will increase.
it puffs out
gas will expand

No. a gas does not expand on a hot day because all of the chemicals compress in order to keep it the size and shape
The gas will expand and the air pressure will decrease because the gas will have more room to move. Gas has no definite shape or volume so it is always trying to expand and move and the higher the temperature the more the energy the gas has to expand.
All of them can expand - for example, when they are heated. Gases usually expand more than solids or liquids.
The gas expand to occupy the volume of the container.
When heat is applied to a gas, its particles gain energy and move faster, increasing their kinetic energy. This causes the gas to expand and its pressure to increase. If enough heat is applied, the gas may change phase and become a plasma.
