A gas bulb of 1L capacity contains `2.0xx10^(21)` molecules of nitrogen exerting a pressure of `7.57xx10^(3)N*m^(-2)`. Calculate the rms velocity and temperature off the gas. If ratio of most probable speed to the root mean square speed in 0.82, calculate the most probable speed of the molecules at this temperature.
