JEE AdvancedPhysicsHeat and ThermodynamicsMultiple correct+4 / −2
In the given P−VP-VP−V diagram, a monoatomic gas (γ=53)\left(\gamma=\frac{5}{3}\right)(γ=35​) is first compressed adiabatically from state AAA to state BBB. Then it expands isothermally from state BBB to state CCC. [Given: (13)0.6≃0.5,ln⁡2≃0.7\left(\frac{1}{3}\right)^{0.6} \simeq 0.5, \ln 2 \simeq 0.7(31​)0.6≃0.5,ln2≃0.7 ].
