Consider equimolar samples of different ideal gases at the same volume and temperature. Gas A has a higher molar mass than gas B. Compare the pressures. Compare the rms speeds. Compare the average kinetic energies. -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. Compare the pressures. Compare the rms speeds. Compare the average kinetic energy. -Consider equimolar samples of the same ideal gas at the same temperature, but different volumes. Sample A has a larger volume than Sample B. Compare the pressures. Compare the rms speeds. Compare average kinetic energy. All of these answers are either A>B, A=B, or A
