Here are the variables that are compared in each of the gas laws:
-
Boyle's Law: Volume, Pressure
- Boyle's Law states that at constant temperature, the volume of a gas is inversely proportional to its pressure.
-
Charles' Law: Volume, Temperature
- Charles' Law states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature.
-
Ideal Gas Law: Pressure, Volume, Temperature, Amount in Moles
- The Ideal Gas Law is an equation of state that relates pressure, volume, temperature, and the number of moles of a gas.
-
Combined Gas Law: Pressure, Volume, Temperature
- The Combined Gas Law combines Boyle's Law and Charles' Law, showing the relationship between pressure, volume, and temperature for a fixed amount of gas.
-
Gay-Lussac's Law: Pressure, Temperature
- Gay-Lussac's Law states that at constant volume, the pressure of a gas is directly proportional to its absolute temperature.
