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. `T_(1) = T_(2)`
B. `T_(3) gt T_(1)`
C. `w_("isothermal") gt w_("adiabatic")`
D. `Delta U_("isothermal") gt Delta U_("adiabatic")`

Answer

A, C, D

Explanation

`T_(1) = T_(2)` because process is isothermal work done in adiabatic process is less than in isothermal because area covered by isothermal curve is more then the area covered by the adiabatic curve In adiabatic process expansion occurs by using internal energy hence it decreases while in iosthermal process temperature remains constant that's why no change in internal energy.
