31m/s is a typical highway speed for a car.
At what temperature do the molecules of nitrogen gas have an rms speed of 31 m/s?
(Answer in K)

  • Physics -

    The subject is Physics, ending with an s.

    The average kinetic energy of any molecule of a gas is (3/2)kT. Set that equal to (1/2)m V^2, and solve for T.

    T = m V^2/(3 k)

    m is the mass of a nitrogen molecule and k = 1.38*10^-23 joule/K
