Dropdown

Gases can be compressed because there is a

amount of empty space between the particles. Once the pressure causing compression is removed, gases will

to fill up the volume of the container.

Multiple Choice

Multiple Choice

Effusion is

used to describe the combustibility of a gas.

ability of a gas to escape through a tiny opening

what occurs after diffusion.

Multiple Choice

Dalton's Law states...

that at a constant temperature the volume of a confined ideal gas varies inversely with its pressure.
