Pak 77 CAREER INSTITUTE MOTA HAIMITRIN An ideal gas undergoes through following cyclic process 1 2 Reversible adiabatic compression from P V T to P V T 2 3 Reversible isochoric heating from P V T to P V T 3 4 Reversible adiabatic expansion from P V Tato PVT 4 1 Reversible isochoric cooling from PVT to P V T Efficiency of the cycles is A 1 B 1 D 1 Q4 11 Q C 1 78 An ideal gas initially at PV T is expanded isothermally to twice it s volume then compressed at constant pressure to have the original volume V Finally the gas is heated at constant volume to get original temperature what is correct A P V diagram for the process is B Total heat supplied is 0 193 PV C Net work is done by the gas D Interal energy remain same during the who 79 The spontaneity means having the potential to proceed without the assistance of external a hec
