Compressibility Compressibility is a measure of how much the volume of matter decreases under pressure.

Compressibility Gases are easily compressed because of the space between the particles in a gas.

Factors Affecting Gas Pressure

Factors Affecting Gas Pressure

Boyle’s Law: Pressure and Volume Boyle’s law states that for a given mass of gas at constant temperature, the volume of the gas varies inversely with the pressure.

Boyle’s Law: Pressure and Volume

Factors Affecting Pressure

Gay-Lussac’s Law: Pressure and Temperature Gay-Lussac’s law states that the pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant.

Charles’s Law: Temperature and Volume Charles’s law states that the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant.

Charles’s Law: Temperature and Volume

The Combined Gas Law The combined gas law describes the relationship among the pressure, temperature, and volume of an enclosed gas.

Ideal Gas Law The ideal gas constant (R) has the value 8.31 (L*kPa)/(K*mol).
