Thermodynamics Question 293

Question: A gas is expanded from volume V0 to 2V0 under three different processes. Process 1 is isobaric process, process 2 is isothermal and process is adiabatic. LetΔU1 , ΔU2 and ΔU3 be the change in internal energy of the gas is these three processes. Then-

Options:

A) ΔU1>ΔU2>ΔU3

B) ΔU1<ΔU2<ΔU3

C) ΔU2<ΔU1<ΔU3

D) ΔU2<ΔU3<ΔU1

Show Answer

Answer:

Correct Answer: A

Solution:

[a] Since volume is same in all three process therefore temperature will be least having least pressure.
