A rigid, sealed container holds a fixed number of molecules of an ideal gas initially in thermal equilibrium at absolute temperature \(T_1\). The gas is then heated to a higher absolute temperature \(T_2\), where \(T_2 > T_1\), without any gas escaping. Which of the following graphs best represents the molecular speed distribution curves of the gas at temperature \(T_1\) (solid curve) and temperature \(T_2\) (dashed curve)?
