Question

$P-T$ diagram is shown in figure. Choose the corresponding $V-T$ diagram.

• A.
• B.
• C.
• D.

Answer 1

Answer: (D)

In the process $BC$, the slope of PT graph remains constant. It means that the process $BC$ is isochoric. the pressure at $B$ is less so the volume at $B$ will be larger than $A$ :
$<br/>V_B>V_A<br/>$
Whereas the volume at different points can be expressed as:
$<br/>V_B=V_C,V_D>V_C<br/>$
