Question 9: Thermodynamics & KTG

Question

An ideal gas of mass $m$ in a state $A$ goes to another state $B$ via three different processes as shown in figure. If $Q_1, Q_2$ and $Q_3$ denote the heat absorbed by the gas along the three paths, then

Accepted Answer

Initial and final states are same in all the process.
Hence, $\Delta U=0$ is same for each case.
$	herefore \Delta Q=\Delta W$
Area enclosed by curve with volume.
$\begin{array}{cc}
\because & (	ext { Area })_1<(	ext { Area })_2<(	ext { Area })_3 \\
	herefore & Q_1< Q_2< Q_3
\end{array}$

Answer

$Q_1< Q_2< Q_3$

Answer

$Q_1< Q_2=Q_3$

Answer

$Q_1=Q_2 >Q_3$

Answer

$Q_1>Q_2 >Q_3$
