Question
Two samples 1 and 2 are initially kept in the same state. The sample 1 is expanded through an isothermal process where as sample 2 through an adiabatic process upto the same final volume. The final temperature in process 1 and 2 are T1 and T2 respectively, then
Options
A.T1 > T2
B.T1 = T2
C.T1 < T2
D.The relation between T1 and T2 cannot be deduced.
Solution
For adiabatic
T Vγ−1 = C (γ > 1) ........(iii)
For isothermal T = cost .....(ii)
From (i) and (ii)
T2 < T1
T Vγ−1 = C (γ > 1) ........(iii)
For isothermal T = cost .....(ii)
From (i) and (ii)
T2 < T1
