Question

Assuming that pollen grains are spherical and have a density of 1100 $$kg/m^{3}$$, calculate the rms speed of a pollen grain at a temperature of 25°C if it behaves like an ideal gas. The diameter of a typical pollen grain is 20 μm.

Accepted Answer

5.17 × $$10^{-5} m/s$$

Answer

2.05 × $$10^{-5} m/s$$

Answer

1.39 × $$10^{-3} m/s$$

Answer

7.19 × $$10^{-3} m/s$$
