A rigid, closed container holds a \(1.0 \text{ mol}\) sample of \(\text{Ne}(g)\) at \(298 \text{ K}\). The Maxwell-Boltzmann distribution curve representing the molecular speeds of the sample at \(298 \text{ K}\) is shown below. The gas is subsequently heated to \(596 \text{ K}\). Which of the following predictions best describes the change in the average kinetic energy of the gas molecules and the appearance of the speed distribution curve at \(596 \text{ K}\)?
