One mole of an ideal monoatomic gas at temperature T and volume 1L expands to 2L against a constant external pressure of one atm under adiabatic conditions, then final temperature of gas will be :
A
T + 
B
T – 
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Δ U = W
nCv (T 2 – T ) = – P × (V 2 – V 1 )
R (T 2 – T) = – 1
T 2 = T –
