How do gas expand?

Answer 1

Because of diffusion. (molecules move from an area of high concentration to low concentration)

Answer 2

As heat is put into a gas, the molecules gain energy and move faster and faster (the temperature goes up). The faster they move the less the intermolecular forces become so the further they can move away from each other

Answer 3

Gases do expand, but they also contract (get smaller and more compressed) depending on the surrounding gas pressure(the force a gas produces on the objects that are inside the gas) so that the two pressures are equal to each other. For example, if the gas pressure in a balloon is more than the air pressure(the pressure of the gas of the air) the gas inside the balloon will expand.

Answer 4

Yes, it does. This is because the molecules move around the most and are more free to move since gas has no definite volume

Answer 5

*if its volume is not limited by anything

*when its temperature goes up and having above statement, it expands faster.

Answer 6

Yes; this is one of the basic properties of a gas.

Answer 7

yes they do because their molecules move at high speed

Answer 8

Gaz Expand when heated (Charles' Law) or the pressure is reduced (Boyle's Law without heat participation).
