Question

Which of the following graphs is not possible for a fixed amount of ideal gas on moving from initial state A to final state B:

• A.
• B.
• C.
• D. None of these

Answer 1

The correct option is D None of these

(A)This graph is possible if the temperature of the gas is kept constant and pressure is increased from A to B.
(B) This graph is possible if the temperature of the gas is increased continuously during the process A to B
(C) This graph is possible if during the process $:P\propto \frac{1}{V^2}$
$\because VT$ = constant $\therefore \left(\frac{PV}{nR}\right)=$ constant or $P{V}^2=constant.$
