1.

A sample consisting of `1mol` of a mono-atomic perfect gas `(C_(V) = (3)/(2)R)` is taken through the cycle as shown. `DeltaU` for the process `(2 rarr 3)` isA. `0.00J`B. `+3.40 kJ`C. `-3.40 kJ`D. None of these

Answer» In conversion from state `2` to state `3`
`DeltaT = T_(2) - T_(1) = 273 - 546 =- 273 K`
`C_(V) = (3)/(2)R`
`:. DeltaU = nC_(V) DeltaT = 1 xx (3)/(2) xx 8.314 xx (-273)`
`=- 3.40 xx 10^(3)J`
