Consider equimolar samples of different ideal gases at the same volume and temperature. Gas A has a higher molar mass than gas B.

Consider equimolar samples of the same ideal gas at the same volume, but different temperatures. Sample A is at a higher temperature than sample B.

Consider equimolar samples of the same ideal gas at the same temperature, but different volumes. Sample A has a larger volume than sample B.

FOR ALL:

Compare the pressures.

Compare the rms speeds.

Compare the average kinetic energies.
