18 Gas Laws SAQ1

The spontaneous spreading out of a substance due to the natural movement of its particles.

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

Avogadro's Law states that equal volumes of gases, under the same conditions of temperature and pressure, contain equal numbers of molecules.
