18 Gas Laws: SAQ2

is the spontaneous spreading out of a substance due to the natural movement of the particles of that substance.

When the volumes are measured under the same conditions of temperature and pressure.

The volume of a fixed mass of gas is inversely proportional to the pressure of the gas.
