Question

Five samples of helium gas are described in the table below. Rank the samples in order of increasing average kinetic energy of the atoms in them. That is, select " 1 " next to the sample in which the helium atoms have the lowest average kinetic energy. Select " 2 " next to the sample in which the helium atoms have the next lowest average kinetic energy, and so on. \begin{tabular}{|c|c|c|c|} \hline \multicolumn{3}{|c|}{ sample } & \begin{tabular}{c} average kinetic \\ energy of atoms in \\ sample \end{tabular} \\ \hline amount & pressure & temperature & \\ \hline 2.1 mol & 1.8 atm & \( -38 .{ }^{\circ} \mathrm{C} \) & \( \square \) \\ \hline 1.5 mol & 2.7 atm & \( -55 .{ }^{\circ} \mathrm{C} \) & \( \square \) \\ \hline 2.8 mol & 2.4 atm & \( -45 .^{\circ} \mathrm{C} \) & \( \square \) \\ \hline 1.8 mol & 1.0 atm & \( -30 .{ }^{\circ} \mathrm{C} \) & \( \square \) \\ \hline 1.6 mol & 1.5 atm & \( -31 .{ }^{\circ} \mathrm{C} \) & \( \square \) \\ \hline \end{tabular}
