Question 971: Thermodynamics & KTG

Question

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.

Then the correct relation is :

Accepted Answer

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)

Answer

$$P_3>P_2>P_1$$

Answer

$$P_1>P_3>P_2$$

Answer

$$P_2>P_1>P_3$$

Answer

$$P_1>P_2>P_3$$
