1 mole of NH3 gas at 27 0 C is expanded in reversible adiabatic condition to make volume 8 times ( 
= 1.33). Final temperature and work done respectively are:
Text Solution
Verified by ExpertsThe correct answer is:
A
T 1 V 1 γ–1 = T 2 V 2 γ–1 
300 × V 1/3 = T 2 (8V) 1/3
T 2 =150 K
W = nC v (T 2 – T 1 ) = 1 × 3 R (150 –300) = 3 × 2 (–150) = –900 cal
