Question

At what temperature is the root mean square speed of an atom in an
argon gas cylinder equal to the rms speed of a helium gas atom at-
20°C ?
(atomic mass of Ar=39.9u,He=4.0u)
​

Answer 1

Answer:

Solution : Let C and C' be the r.m.s. Velocity of argon and a helium gas atoms at temperature TK and T'K respectively. Since, C=C′,∴,√3RT39.9=√3R×2534orT

Answer 2

Let C and C' be the r.m.s. Velocity of argon and a helium gas atoms at temperature TK and T'K respectively. Since, C=C′,∴,√3RT39.9=√3R×2534orT=39.9×2534.
