Blank 1: Continuing with the system from Problem 1 (make sure you solve problem 1before working on this one), if you now cool the gas to the original temperature while keeping the volume fixed, what is the change in total internal energy after performing both the expansion from Problem 1 and the cooling just described, in kJ? Blank 2: What is the work w done in this second step in kJ? Blank 3: What is the heat q for the entire process (Problem 1 and Problem 2) in kJ?
