Question

a) What is v(average) for O2 at sea level?
b) What is v(average) for N2 at sea level?
d) What is v(average) for H2 at sea level?

Answer 1

Do you know the relation between temperature and the mean speed of a molecule?

Answer 2

The average kinetic energy of a gas,
\[ KE_{average} = \frac{3}{2}kT \]
where T is temperature in Kelvin.

Now as \( KE = \frac{1}{2}mv^2 \), this gives you a way to solve for \( v_{average} \).

Answer 3

Thanks, helped a lot!
