Boyle's Law

For a fixed mass of gas at constant temperature, volume is inversely proportional to pressure.

Charles's Law

At constant pressure, the volume of a fixed mass of gas is directly proportional to its temperature.

Gay-Lussac's Law

At constant volume, the pressure of a gas is directly proportional to its Kelvin temperature.

Ideal Gas Law

PV = nRT. Relates pressure, volume, moles, ideal gas constant, and temperature.

Study Notes

Gas Laws

  • Boyle's Law states that for a given mass of gas at constant temperature, the volume of the gas varies inversely with pressure.
  • According to Charles's Law, if the pressure is kept constant, the volume of a fixed mass of gas will change in direct proportion to the temperature on the Kelvin scale.
  • Gay-Lussac's Law states that the pressure of a gas is directly proportional to its Kelvin temperature if the volume is kept constant.

Ideal Gas Law

  • The equation for the ideal gas law is PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is temperature in Kelvin.

Dalton's Law of Partial Pressures

  • According to Dalton's Law, the total pressure exerted by a mixture of gases at constant volume and temperature is the sum of the partial pressures of each gas.
