A rigid container holds a fixed number of molecules of an ideal gas initially at temperature \(T_1\). The Maxwell-Boltzmann distribution of molecular speeds at temperature \(T_1\) is shown in the graph, where \(v_0\) represents a speed significantly higher than the most probable speed. The gas is then heated to a higher temperature \(T_2\). Which of the following correctly describes the change in the distribution curve and the fraction of molecules with speeds greater than \(v_0\)?
