Question

A cyclic process ABCA is shown in the V-T diagram. Process on the P-V diagram is

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

From the given VT diagram, we can see that
In process AB, $V\approx T\therefore$ Pressure is constant (As quantity of the gas remains same)
In process BC, V = constant and in process CA, T = constant
$\therefore$ These processes are correctly represented on PV diagram by graph (c).
