Which equation agrees with the ideal gas law?

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 .

The answer is true for your question.
