I need help solving number 11. In question 1, they say U=(3/2)PV
I found work on the gas as -3/2PV, so therefore Q should be 6/2PV but the answer key says 6PV.
The temperature of 3.00 mol of a gas with CV = 6.00 cal/mol K is to be raised 50.0 K. If the process is at constant volume, what are (a) the energy transferred as heat Q, (b) the work W done by the gas, (c) the change Eint in internal energy of the gas, and (d) the change K in the total translational kinetic energy? If the process is at constant pressure, what are (e) Q, (f) W, (g) Eint, and (h) K? If the process is adiabatic, what are (i) Q, ( j) W, (k) Eint, and (l) K?
