In an experiment, the viscosity of the gas was found to be 2.25 x 10^-4 CGS units. The RMS velocity of the molecules is 4.5 x 10^4 cm/s. The density of the gas is 1 gm per liter. Calculate the mean free path of the molecules.© BrainMass Inc. brainmass.com October 24, 2018, 5:19 pm ad1c9bdddf
A molecule has a finite size and moves randomly inside the container. While doing so, it collides with other molecules and the walls of the container. The path covered by a molecule between any two consecutive collisions is a straight line, and is called the ...
Very detail answer with easy to understand steps. It will enable you to do similar problems yourself.
Quasistatic isothermal expansion and free expansion
During the quasistatic isothermal expansion of a monoatomic ideal gas, how is the change in entropy related to the heat input Q by the simple formula: ΔS = Q/T?
Why isn't this valid for the free expansion process?View Full Posting Details
