Maybe I did word it wrongly, my textbook said "at constant temperature" instead of what i said "only applies to constant temperature". I've attached the screenshot of my textbook's explanation on adiabatic process here (I highlighted the related part) imgur.com/a/UiLoDo3 But from my understanding, "at constant temperature" should also mean "only applies when there is a constant temperature"? | |

| Oct 19, 2018 at 19:46 | comment | added | Bøbby Leung | Thanks for the input. You mentioned the 'excellent approximation equation' which there's something I'm not so sure about. My textbook mentioned that relationship only applies to when there is a constant temperature (but that can never be the case for an adiabatic process I believe?) | |
