I am a little confused about the nature of an isothermal process. If we compress a gas and it is an isothermal process, we know the temperature has to increase, therefore q is increasing. For this process to be isothermal, the gas then must have done work on the compression, but this work is negative which allows our delta E to be 0?

Hey Josh, thanks for your question!

I think there might be a mix up with some concepts. An isothermal condition refers to no change in temperature. The system does not change in internal energy and since delta U = Q-W and delta U = 0, Q = W. Any heat that is generated is essentially utilized in work. The temperature is kept constant.

Hope this helped! Cheers, and happy studying!
