The reversible expansion of an ideal gas...

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?

A

`T_(1) = T_(2)`

B

`T_(3) gt T_(1)`

C

`W_("isothermal") gt W_("adiabatic")`

D

`DeltaU_("isothermal") gt DeltaU_("adiabatic")`

Text Solution

Verified by Experts

The correct Answer is:
acd
In adiabatic expansion temperature always decreases. In case of expansion
`W_("isothermal") gt W_("adiabatic")`
