Question
The reversible expansion of an ideal gas under adiabatic and isothermal conditions is shown in the figure.Which of the following statement(s) is (are) correct?
Options
A.T3 > T1
B.T1 = T2
C.wisothermal > wadiabatic
D.ᐃUisothermal > ᐃUadiabatic
Solution
T1 = T2 because process is isothermal.
Work done in adiabatic process is less than in isothermal process because area covered by isothermal curve is more than the area covered by the adiabatic curve.
In adiabatic process expansion occurs by using internal energy hence it decreases while in isothermal process temperature remains constant that′s why no change in internal energy.
