Consider a process in which an ideal gas changes from state 1 to state 2 in such a way that its temperature changes from 300 K to 200 K. (c) Does the change in the internal energy, ΔE, depend on the particular pathway taken to carry out this change of state?

Video transcript

Hey everyone in this example, we have a true or false prompt. We're told that the change in internal energy DELTA E. Of an ideal gas that goes from State one to State two as temperature goes from 78 kelvin 2 to 89 kelvin is path dependent. Now we want to recall that change in internal energy, which is represented as delta E, is going to be a state function and we want to recall that state functions are going to be not dependent on the path, so they're not path dependent. And so we would say that therefore the statement, it's false. So false would be our final answer to complete this example. I hope that everything I reviewed was clear. If you have any questions, leave them down below and I will see everyone in the next practice video.
