One mole of an ideal gas expands adiabatically from temperature T1 to temperature T2. The work done by the gas is
Select one:

Detailed Solution for First Law Of Thermodynamics MCQ Level – 2 (Part - 1) - Question 1

 

We have ΔU = ∫(T2 to T1) CvdT − Cv(T2−T1)
Since the process is adiabatic, dQ = 0
ΔQ = ΔU + ΔW

ΔQ = ΔU + ΔW
∴ ΔW = −ΔU

= −Cv(T2−T1)

= Cv(T1−T2)
