prove average total kinetic energy = 2kT for gas molecules crossing a spherical area, with the following equations.
At what frequency do molecules (diameter 290 pm) collide in (an ideal) oxygen gas (O2) at temperature 400 K and pressure 2.00 atm?
Real gases
For helium gas, the critical temperature is Tk=5.2K and the critical pressure is Pk=0.23x10^6 Pa. Assuming that the helium gas obeys the Van der Waals equation, calculate the Van der Waals constants a and b, and the density of helium in the critical state.

- So each four dot shows four different states for an ideal gas. P is the pressure and the other one is the density of the gas. Is temperature of state 1 less or greater than the state 2? Can you please explain why?arrow_forwardIf one could somehow (pretend) get the temperature of an ideal gas to be absolute zero (i.e., 0 K) which of the following properties of the molecules of that gas would not be zero? (If you do not like pretending, for an ideal gas which of the following properties of the molecules does not have to be close to zero when the temperature is close to absolute zero?) Group of answer choices a) Average speed would not go to zero. b) Average momentum would not go to zero. c) Average kinetic energy would not go to zero. d) More than one of these would not go to zero. e) None of these (that is, they would all go to zero).arrow_forwardCylinder A contains oxygen (O2) gas, and cylinder B contains nitrogen (N2) gas.

- Consider a gas filling two connected chambers that are separated by a removable barrier (Fig. P20.68). The gas molecules on the left (red) are initially at a higher temperature than the ones on the right (blue). When the barrier between the two chambers is removed, the molecules begin to mix and move from one chamber to the other. a. Describe what happens to the temperature in the left chamber and in the right chamber as time goes on, once the barrier is open. Discuss in terms of the mixing of the molecules from each gas. b. Describe what happens to the most probable speed and average speed in the left chamber and in the right chamber as time goes on, once the barrier is open. Do they increase or decrease by the same factor? Explain.

Because these two gases don't react chemically at or below 2000 psi, at typical room temperatures they form a homogeneous single gas phase, which can be considered an ideal gas. If the temperature drops below -6∘C, however, N2O may begin to condense out of the gas phase. Then any gas removed from the cylinder will initially be nearly pure O2; as the cylinder empties, the proportion of O2 will decrease until the gas coming from the cylinder is nearly pure N2O. In a test of the effects of low temperatures on the gas mixture, a cylinder filled at 27.0 ∘C to 2000 psi (gauge pressure) is cooled slowly and the pressure is monitored. What is the expected pressure at -5.00∘C if the gas remains a homogeneous mixture?arrow_forward
