2 A 1.0 mol sample of He (9) at 25°C is mixed with a 1.0 mol sample of Xe (9) at 50'C. Which of the
following correctly predicts the changes in average kinetic energy and the aXekale speed of
the atoms that will occur as the mixture approaches thermal equilibrium?

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
