I've read back and forth in my chapter and tried consulting with my forumla sheet, but I cannot seem to find the correct formula. I bet I am looking at this question wrong, but I am fairly sure I need to use the -100 kJ for something to find the final volume and pressure , along with the given pv2=constant.
Basically, given the information below, how would you go about starting to solve this?
A mass of gas at an initial pressure of 28 bar, and with an internal energy og 1500 kJ, is contained in a well-insulated cylinder of volume 0.06m3. The gas is allowed to expand behind a piston until it's internal energy is 1400 kJ; the law of expansion is pv2=constant. Calculate:
1) the work done (Already calculated, -100kJ)
2) the final volume
3) the final pressure
