1.	5 Moles of an ideal gas at 100 K are allowed to undergo reversible compression till its temperature becomes 200 K. If Cv = 28 JK-1 mol-1, calculate ∆U and ∆pV for this process. (R = 8.0 JK-1 mol-1)
A.	∆U = 14 kJ; ∆(pV) = 18 kJ
B.	∆U = 14 J; ∆(pV) = 0.8 J
C.	∆U = 14 kJ; ∆(pV) = 4 kJ
D.	∆U = 28 kJ; ∆(pV) = 0.8 kJ
Answer» D. ∆U = 28 kJ; ∆(pV) = 0.8 kJ
