Question
If the density of nitrogen is 1.25 kg/m3 at a pressure of 105 Pa, find the root mean square velocity of nitrogen molecules.
Solution
Vrms = `sqrt((3"P")/ρ) = sqrt((3 xx 10^5)/(1.25))` = 489.89 m/s
Notes
[Note - Since density value given in question is of nitrogen, question is modified to obtain RMS velocity of nitrogen molecules.]
