Web(b) Find the rms speed of a nitrogen molecule (N2) at this temperature. Strategy (a) The known in the equation for the average kinetic energy is the temperature: – K = 1 2 m– v2 = 3 2kBT. Before substituting values into this equation, we must convert the given temperature into kelvin: T = (20.0 + 273)K = 293K. WebFeb 19, 2014 · The average speed at which the electrons move down a wire is what we call the "drift velocity". Even though the electrons are, on average, drifting down the wire at the drift velocity, this does not mean that the effects of the electrons' motion travels at this velocity. Electrons are not really solid balls.
