The mean speed of the molecules of a hydrogen sample equals the mean speed of the molecules of a helium sample. Calculate the ratio of the temperature of the hydrogen sample to the temperature of the helium sample.

Explanation

`V_avg = (sqrt(8RT))/(sqrt(piM)) = (sqrt(8 xx 8.3 xx300)/(3.14 xx 0.032))`
` Now, (8RT_1)/(pi xx 2)= (8RT_2)/(pi xx 4)`
` rArr T_1/T_2 =1/2`
