Question

one mole of ideal gas is allowed to expand reversibly and adiabatically from temperature 27 degree if the work done by the gas in the process is 3 kilojoule the final temperature will be equal to

Answer 1

W= nCv∆T

W/nCv= T2 - T1

T2 = W/nCv +T1

T2 = 150k

Solve it yourself... I just gave you the idea
