Question

The ratio between The RMS velocity of h2 at 50 Kelvin and that of o2 at 800 Kelivin

Answer 1

the formula of RMS velocity is √(3RT/M) where R is universal gas constant ,T is temperature of the gas , M is the molar mass of the gas in this case the RMS velocity of H2 is √(3×R×50/2) always temperature is taken in kelvins for calculation now RMS velocity of O2 is √(3×R×800/32) now when we take ratio of both of these we get √(3×R×50×32/3×R×800) after simplification we get 2:1 ratio
