The following graph represents the $$T\text -V$$ 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 elation is :
1. $$P_1>P_3>P_2$$
2. $$P_2>P_1>P_3$$
3. $$P_1>P_2>P_3$$
4. $$P_3 > P_2>P_1$$
