Question

What is the average speed (actually the root-mean-square speed) of a neon atom at 27°C?

Answer 1

Answer:

432m/s

Explanation:

The rms speed (u) is related to the temperature (T) and molecular weight (M) by the expression

u=

M

3RT

u=

40×10

−3

kg/mol

3×8.314J/molK×(27+273.15)K

u=432.2m/s

Hence, the rms speed is 432.2 m/s
