Practice UPCET / UPSEE RMS Speed in the app →The **rms speed** of gas molecules at absolute temperature $T$ is:The rms speed of N₂ at 300 K (M = 28 g/mol) is approximately (use $R = 8.314$ J/(mol·K)):If the temperature of a gas is doubled (at constant volume), the rms speed changes by a factor of:The rms speed of helium atom at 300 K is approximately (M_He = 4 g/mol):
