Q1 A) (2Marks)Heat in the anount of 7.5KJ is addad to a closed sytem while 3U12K ). How much eneryy is transferred as work. For a process caasing the ame change of suee but for which the work is zero how mach beat is tranaferred. B) (4Marks) I mole of air is heated revervibly at constant pressure from 300K and 1 bar ustil it volume triples. Calculate W,Q. U,H for the process. Assame PVTT-83.14 bar cm'? mol.K,Cp=29J/molK C)(8Marks) An ideal gas (C1(5/2)R and C1=(3/2)R(R=5.3U/moleK) is changed from P1=1 bar and V1=12m to P212b ar and V21m3 by the following reversible process. a) Isothermal compression. b) Adiabatic compression followed by cooling at constant pressure. c) Adiabatic compression followed by cooling at constant volume. d) Heating at constant volume followed by cooling at constant pressure. A) Sketch the paths of all process in a single PV diagam B) Calculate Q. W, U,H for each of these processes
