gas laws

Boyles law

At a constant temperature the volume of a fixed mass of gas is inversely proportional to its pressure

Charles law

At constant pressure, the volume of a fixed mass of gas is inversely proportional to its temperature in kelvin

Gay Isaac’s law of combining volumes

In a reaction between gases, the volumes of the reacting gases and volumes of any gaseous products are in the ratio of small whole numbers, providing the volumes are measured at the same temperature and pressure

Avogadros law

Equal volumes of gases under the same conditions of temperature and pressure contain equal numbers of molecules.

Kinetic theory 3 examples

1. There are no attractive or repulsive forces between the molecules of a gas. 2.when the particles collide, the collisions are perfectly elastic.(no loss of kinetic energy. 3.The gas particles are so small and widely separated the actual volume is negligible the space they occupy.

Ideal gas

An ideal gas is one that obeys all the assumptions of kinetic theory of gases under all conditions of temperature and pressure.
