The r.m.s. velocity of hydrogen is sqrt(7) times the r.m.s. velocity 1.0 g cm^(-3) and that of wate vapours is 0.0006 g cm^(-3), then the volume of water molecules in 1 L of steam at this temperature is

Answer»

`T(H_(2)) = T(N_(2))`
`T(H_(2)) gt T(N_(2))`
`T(N_(2)) gt T(H_(2))`
`T(H_(2)) = SQRT(7)T(N_(2))`

Solution :`sqrt((3RT_((H_(2))))/(2)) = sqrt(7)sqrt((3RT_((N_(2))))/(28))`
or `(3RT_((H_(2))))/(2) = 7 xx (3RT_((N_(2))))/(28)`
or `T_((N_(2))) = 2T_((H_(2)))`
`:. T_((N_(2))) gt T_((H_(2)))`
