A vessel contains 5900 oxygen molecules at 520 K having Maxwell-Boltzman distrubution function. The universal gas constant is 8.31451 J/K mol. Determine the most probable speed if the molecular mass of oxygen is 0.032 kg/ mol. Answer is m/s. Find the average speed for the molecules of the gas in m/s. Find the root-mean-square speed for the particles in the gas in m/s. I added more points since this is multiple questions. Thanks!
Repeat Problem 3, but this time, treat the steam as an ideal gas
with cp = 2.083 kJ/kg-K, which is its value at about 700 K. (You
will need to determine Rg = Ru/MWwater, with MWwater = 18.0
kJ/kg-K, as well as k = cp/cv). You’ll find that the ideal gas
model is not too bad for water vapor under these conditions.
Solve the second one plz
