A reversible cyclic process for an ideal gas is shown below, Here, P, V, and T are pressure, volume and temperature, respectively. The thermodynamic parameters q, w, H and U are heat, work, enthalpy and internal energy, respectively.
The correct option(s) is (are) (2018)
The correct option(s) is (are) (2018)
- qAC = \(\Delta \mathrm{U}_{\mathrm{BC}}\) and wAB = P2 (V2 – V1)
- \(\mathrm{w}_{\mathrm{BC}}=\mathrm{P}_{2}\left(\mathrm{~V}_{2}-\mathrm{V}_{1}\right) \text { and } \mathrm{q}_{\mathrm{BC}}=\Delta \mathrm{H}_{\mathrm{AC}}\)
- \(\Delta \mathrm{H}_{\mathrm{CA}}<\Delta \mathrm{U}_{\mathrm{CA}} \text { and } \mathrm{q}_{\mathrm{BC}}=\Delta \mathrm{H}_{\mathrm{AC}}\)
- \(\mathrm{q}_{\mathrm{BC}}=\Delta \mathrm{H}_{\mathrm{AC}} \text { and } \Delta \mathrm{H}_{\mathrm{CA}}>\Delta \mathrm{U}_{\mathrm{CA}}\)
Answer
(B) w _ BC = P _ 2 ( ~V _ 2 - V _ 1 ) and q _ BC = H _ AC, (C) H _ CA < U _ CA and q _ BC = H _ AC
