A line graph displaying molecular speed distributions on bare axes without gridlines. The horizontal axis is labeled 'Molecular speed (m/s)' and the vertical axis is labeled 'Relative number of molecules'. Both axes originate at (0, 0). Two curves are plotted starting at the origin: Curve 1 (rendered as a solid curve) rises sharply to a tall, narrow peak located at a relatively low speed value, then decreases and tapers off. Curve 2 (rendered as a dashed curve) rises more gradually to a lower, broader peak positioned further to the right at a higher speed value, with a long tail extending to high speeds. A legend located in the upper right quadrant indicates: solid line = Gas 1; dashed line = Gas 2. No other lines, labels, text, or annotations appear.
Maxwell-Boltzmann molecular speed distributions for Gas 1 and Gas 2 at \(300 \text{ K}\).
The graph below shows the Maxwell-Boltzmann molecular speed distributions for \(1.00 \text{ mol}\) samples of two pure gases, Gas 1 and Gas 2, in separate identical containers at \(300 \text{ K}\).

Which of the following claims about the two gases is best supported by the data in the graph?
