Why can gases take the shape of an container?

Answer 1

The process by which gases take the shape of their container is diffusion, in which the gas particles move from an area of higher concentration to an area of lower concentration, until a dynamic equilibrium is reached.

Answer 2

Basically, gases quickly take the shape of a container into which they are released because of a physical phenomenon called diffiusion. Diffusion is the tendency of a substance (gas or liquid) to move from a space where it is more concentrated into a space where it is less concentrated. Gas molecules are in a constant state of motion and when confined to a tighter space, have a higher energy level. But nature tends to want to be at a lower energy level, or at a state of rest. So given the opportunity, a gas will expand to reduce its potential energy, which results in diffusion.

Answer 3

The intermolecular forces in gases are extremely weak.

Answer 4

I believe it is diffusion.
