Question

2.)1.0 mol sample of an ideal monatomic gas originally at a pressure of 1 atm undergoes a 3-step process as follows:

                 (i)         It expands adiabatically from T1 = 588 K to T2 = 389 K

                 (ii)        It is compressed at constant pressure until its temperature reaches T3 K

                 (iii)       It then returns to its original pressure and temperature by a constant volume process.

A). Plot these processes on a PV diagram

B). Determine the temperature T3

C). Calculate the change in internal energy, work done by the gas and heat added to the gas for each of these three processes

D). Calculate the change in internal energy, work d0ne by the gas and heat added to the gas for the complete cycle.
