Question

1 mole of nh3 gas at 27c is expanded in adiabatic condition to make its volume 8 times( gamma =1.33). final temperature and work done respectively are?

Answer 1

n1 = 1

T1 = 273 + 27 = 300 k

Since the process is adiabatic

So

pressure will be constant

Thus pressure = P

Also V1 = V

Thus       P V1 = n1 RT1

              P V = R 300

according to question

V2 = 2V

Thus       P V2 = n2 R T2

              P 2V = R T2

Thus       T2 = 600K
