And these two conditions are under the same pressure and number of moles, that means our constant will be the same. And so I can say V one over T one equals V two over t two equals that same constant. So once again, for a gas sample with two different sets of T's and Vs for two different conditions, this is our law. This is our Charles Law. Now, whenever we talk about gases, and we talk about these different laws that revolve around gases, our temperature is never in Celsius, it's only in Kelvin. And that means we have to convert Celsius to Kelvin.
