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 relation is:
1.
\(P_1>P_3>P_2 \)
2.
\(P_2>P_1>P_3 \)
3.
\( P_1>P_2>P_3\)
4.
\(P_3 > P_2>P_1\)
