Following figure shows two processes A and B for a gas. If Δ Q_A and Δ Q_B are the amount of heat absorbed by the system in two cases, and Δ U_A and…
Following figure shows two processes A and B for a gas. If $\displaystyle \Delta \mathrm{Q}_{\mathrm{A}}$ and $\displaystyle \Delta \mathrm{Q}_{\mathrm{B}}$ are the amount of heat absorbed by the system in two cases, and $\displaystyle \Delta \mathrm{U}_{\mathrm{A}}$ and $\displaystyle \Delta \mathrm{U}_{\mathrm{B}}$ are changes in internal energies, respectively, then :
Official answer
(3)
$\displaystyle \Delta \mathrm{Q}_{\mathrm{A}}>\Delta \mathrm{Q}_{\mathrm{B}}, \Delta \mathrm{U}_{\mathrm{A}}=\Delta \mathrm{U}_{\mathrm{B}}$
