При 0° С молекулы кислорода имеют среднюю скорость 460 м/с. Какова при этой температуре средняя скорость молекул азота?

Question

At 0 ° C, oxygen molecules have an average speed of 460 m / sec. What is at this temperature, average speed of nitrogen molecules?

Answer 1

Average speed (Vav) at a given temperature is proportional to M^-1/2,
where M is the molecular mass.

Therefore

Vav(N2) = Vav(O2) * sqrt(32/28)
= 1.069*460 = ___ m/s
