In a region of space the density is 10 helium atoms per $c m^{3}$ and the temperature is 10 K. Find the rms speed of the atoms in m/s (nearest integer, $m_{He} = 4 \times 1.66 \times 1 0^{- 27}$ kg).

Answer:

250.00

Solution:

$v_{r m s} = \frac{3 k T}{m} = \frac{3 \times 1.38 \times 1 0 ^{- 23} \times 10}{6.64 \times 1 0 ^{- 27}} = 250$
