Calculate r.m.s velocity of nitrogen molecules at `27^@C` and 76 cm of mercury pressure.

R.M.S. velocity of nitrogen molecules at N.T.P. is

The molecules of a given mass of a gas have root mean squar speeds of 100 ms^-1 at 27^@C and 1.00 atmospheric pressure. What will be the root mean square speeds of the molecules of the as at 127^@C and 2.0 atmospheric pressure?

AT what temperature is the r.m.s. velocity of a hydrogen molecule equal to that of an oxygen molecule at 47^@C ?

Calculate volume occupied by two moles of gas at 27^@C and under a pressure of 1 atmosphere.

The r.m.s velocity of gas molecules is 300 ms^-1 The r.m.s velocity of molecules of gas with twice the molecular weight and half the absolute temperature is
