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. \(P_3 > P_2>P_1\)
