Question

Q2)Two moles of a diatomic ideal gas is shown to undergo an enclosed cycle shown in the figure.

A) How much work is done by the gas during the process A to B? B) How much work is done by the gas during the process B to C? C) How much work is done by the gas during the process C to A? D) How much heat is added or removed from the system during the process of A to B? E) How much heat is added or removed from the system during the process of B to C? F) What is the Change in internal energy during the process of A to B? G) What is the change in internal energy during the process of B to C?

Explanation / Answer

Given, n=2

TA=PV/nR=20*1/2*8.314=1.20K

TB=20*3/2*8.314=3.61 K

TC=40*3/2*8.314=7.216

For diatomic gas,CP=7/2 R=29.1 J/K.mol

CV=5/2 R=20.8 J/K.mol
