Answer:
The r.m.s. velocity of a gas molecule is given by:
V= sqr root of 3RT/M
Let the temperature at which the velocity of hydrogen is equal to the velocity of oxygen at 47 degree be T
Therefore,
(V r.m.s.) H = ( V r.m.s.) O
Sqr root of 3RT/2 = sqr root of 3R*(273+47)/32
Squaring both sides we get
3RT/2 = 3R * 320/32
T = 20 Kelvin
