Study Notes

Gas Properties

  • The relationship between the volume and pressure of a gas is inverse, meaning that as the volume of a gas increases, its pressure decreases, and vice versa.

Pressure and Temperature

  • When the temperature of a gas is increased, its pressure also increases, assuming the volume remains constant.

Compressibility of Gases

  • The characteristic property of gases that allows them to be easily compressed is their molecules being widely spaced and free to move, making them highly compressible.

Definition of Pressure

  • Pressure is defined as the force per unit area, typically measured in units such as pascals (Pa) or pounds per square inch (psi).
