NEETPhysicsHeat and ThermodynamicsMCQ+4 / −1

The following graph represents the $T$ - $V$ curves of an ideal gas (where $T$ is the temperature and $V$ the volume) at three pressures $P_1, P_2$ and $P_3$ compared with those of Charles's law represented as dotted lines.

NEET 2024 Physics - Heat and Thermodynamics Question 8 English

Then the correct relation is :

A
$P_3>P_2>P_1$
B
$P_1>P_3>P_2$
C
$P_2>P_1>P_3$
D
$P_1>P_2>P_3$

View written solutionFree

Correct answer: D

At same temperature, curve with higher volume corresponds to lower pressure.

$$\begin{aligned} & V_3>V_2>V_1 \\ & \Rightarrow P_1>P_2>P_3 \end{aligned}$$

(We draw a straight line parallel to volume axis to get this)
