Question

During which of the thermodynamic process represented by PV diagram the heat absorbed by system may be equL to area pv graph

Answer 1

Answer: 2nd

Explanation: because it's an isotherm. Isotherm is a system in which the internal energy remains same. So ∆U=∆Q-∆W

So if ∆U=0 then ∆Q=∆W and ∆W=P∆V, so heat absorbed is equals to area under PV graph.
