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. The following graph represents the T - V curves of an ideal gas (where T is the temperature and V the volume) at three

The following graph represents the T - V curves of an ideal gas (where T is the temperature and V the volume) at three

Then the correct relation is:

Options

A $P_1\gtP_3\gtP_2$
B $P_2\gtP_1\gtP_3$
C $\quad P_1\gtP_2\gtP_3$
D $P_3\gtP_2\gtP_1$

Correct answer

C. $\quad P_1\gtP_2\gtP_3$

Step-by-step solution

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

\begin{aligned} & V_3\gtV_2\gtV_1 \\ & \Rightarrow P_1\gtP_2\gtP_3 \end{aligned}

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