$$P \propto \frac{1}{V}$$
Charles's Law: The volume of a gas is directly proportional to its temperature, when pressure and amount of gas remain constant.
$$V \propto T$$
Avogadro's Law: The volume of a gas is directly proportional to the amount of gas, when pressure and temperature remain constant.
$$V \propto n$$
Gay-Lussac's Law: The pressure of a gas is directly proportional to its temperature, when volume and amount of gas remain constant.
$$P \propto T$$
Ideal Gas Law: Combines all of the above laws and introduces a proportionality constant, R, which is the universal gas constant.
$$PV = nRT$$
Where:
- P is the pressure of the gas
- V is the volume of the gas
- n is the amount of gas in moles
- R is the universal gas constant (0.08206 L atm / mol K)
- T is the temperature of the gas in Kelvin
