The initial state of an ideal gas is represented by the point $a$ on the P-V diagram and its final state by the point $e$ . The gas goes from the state $a$ to the state $e$ by three quasi stationary processes represented by (i) abe (ii) ace (iii) ade. The heat absorbed by the gas is

Options:(select one or more)

Answer:

C, D

Solution:

$Δ U$ is the same for all three paths, so $Q$ follows the work $W =$ area under the path. Path abe encloses more area than ade, and ace less than ade: $W_{abe} > W_{ade} > W_{ace}$ . Hence $Q_{(i)} > Q_{(iii)}$ and $Q_{(ii)} < Q_{(iii)}$ .
