State the Boyle’s Law

Boyle’s Law states that for a fixed amount of gas at constant temperature, the pressure of the gas is inversely proportional to its volume.

State the Charles’ Law

It states that the volume of a fixed mass of gas is proportional to its absolute temperature when the pressure remains constant.

State the Gay-Lussac’s Law

It states that the pressure exerted by a fixed mass of gas at a constant volume is directly proportional to its absolute temperature.

Define “ideal gas”

A hypothetical gas composed of molecules which follow a few rules

State the two assumptions of the ideal gas

A. The volume of individual gas molecules is negligible compared to the container volume

B. There are no intermolecular forces between the gas particles

Define temperature

Is a measure of the average kinetic energy of the particles in a sample of matter
