The figure shows the P-V plot of an ideal gas taken through a
cycle DCBAD then
dks pØ DCBAD

Amaximum temperature will occur during the process C → B → A.Bnegative work is done by the gas in the cycle DCBAD.Cheat flows out of the gas during C → B → A.DAll of the above.

Show answer and solution▾

Since temperature at C and A are same so maximum temperature
occurs at a state between them during process CBA.
Since cycle in PV graph is anticlockwise so work done by gas in
negative.
During CBA work done by gas is negative and [IMAGE] so
[IMAGE]. So heat is released by gas.
