is directly related to the ideal gas law.
The ideal gas law states that:

. Rewriting this gives:

. R is the universal gas constant, so its value is fixed. For a given sample, n is the number of moles of the gas, so its value would be fixed too. This means that the value of

would be a fixed constant as well. Therefore, whatever the initial value

is, it should be equal to the final value
