Figure 3.83 shows two processes $a$ and $b$ between the same two states of a given sample of gas. Let $Δ Q_{1}$ and $Δ Q_{2}$ be the heat absorbed by the system in the two cases ( $a$ and $b$ respectively). Then:

Options:

Answer:

Solution:

$Δ U$ is the same for both paths. The work done is the area under the curve, larger along $a$ . $Q = Δ U + W$ gives $Δ Q_{1} > Δ Q_{2}$ . C.
