Reversible expansion of an ideal gas under isothermal and adiabatic conditions are as shown in the figure. AB → Isothermal expansion AC → Adiabatic expansion Which of the following options is not correct? (Odisha NEET 2019)
A.∆Sisothermal > ∆Sadiabatic
B.TA = TB
C.Wisothermal > Wadiabatic
D.Tc > TA✓ Correct
Explanation
For an ideal gas, internal energy is a function of temperature. Final temperature i.e., TC for adiabatic process is less than its initial temperature i.e., TA ∴ TC < TA
