Question

1 mol of NH3 gas at 27oC is expanded under adiabatic condition to make volume 8 times (g = 1.33). Final temperature and work done, respectively, are

Options

A.150 K, 900 cal
B.150 K, 400 cal
C.250 K, 1000 cal
D.200 K, 800 cal

Solution

T2 = T1 = 150 K
w = - CVDT = - CV(T2 - T1)
= -3 × 2 × (150 - 300)
= 900 cal
