P₁ = initial pressure

P₂ = final pressure

T₁ = initial temperature

T₂ = final temperature.

V₁ = initial volume

V₂ = final volume

All temperature units must be in Kelvin

Volume and pressure units must be the same on both sides of the equation

The combined gas law shows the relation between temperature pressure and volume of a given sample even when they change. it states that the product of the initial volume and pressure divided by the temperature will be the same as the final sample with the same equation. it is arranged like that as pressure and volume are indirectly proportionate but both volume and pressure are directly proportionate to temperature.

P₁ x V₁/T₁ = P₂ x V₂/T₂

P₁ = initial pressure

P₂ = final pressure

T₁ = initial temperature

T2 = final temperature.

All temperature units must be Kelvin

pressure units must be the same on both sides

Gay-Lussac's Law states that the first pressure and the second temperature will be equal to the second pressure and the first temperature. Pressure and temperature are directly proportionate meaning if one increases the other will also increase.

P 1 x T ₂ = P ₂ x T 1
Or T ₁/T ₂ = P ₁/P ₂

V₁ = the original volume

V₂ = the final volume

T₁ = the original temperature

T₂ = the final temperature

All temperature units must be in Kelvin

The volume units used must be the same on both sides.

Charles' law states that the product of the first temperature and the second pressure  with be the same as the product of the second temperature and first volume. The temperature and volume are directly proportionate meaning if one increases the other will also increase

V ₁ T ₂= V ₂ T 1
Or  T ₁/T ₂ = V ₁/V ₂

Boyle's law states that with gasses the product of the volume and pressure of the initial sample will be the same as the products of the final sample. Volume and pressure are inversely proportionate meaning if one increases the other will decrease.
