Two moles of an ideal monoatomic gas undergo a cyclic process starting from state A at a vol. of 1L and a pressure of 2 atm. It expands at constant pressure until the volume is 2.5L (state B), after which it is cooled at constant vol. until its pressure is 1 atm (state C). It is then compressed at constant pressure until its vol. is again 1 L. (state D), after which it is heated at constant volume until it is back in its original state A. Take R=8 j/molK, 1 L = 10^-3 m^3, 1 atm= 10^5 N/m^2.
A.) Draw this cycle on a PV diagram.
B.) Find the temperature in states A and B.
C.) Calc. the chang in internal energy in processes 1 (A to B).
D.) Find the total work done by the gas in one cycle.
E.) What is the change in internal energy for the entire cycle?
