1. The PV diagram below represents a heat pump with 5 moles of gas. Given the additional information that the change in internal energy ΔQ, when the temperature of a gas changes by ΔT is given by the equation ΔU = 3/2nRΔT where n = the number of moles R= 8.31 Jmol-1 K-1Calculate the following: a. the temperature at A, B , C and D b. heat lost from A-B c. heat gained from B-C d. heat gained from C-D e. heat lost...
