Question

A flask contains a mixture of neon (Ne), krypton (Kr), and radon (Rn) gases. Compare (a) the average kinetic energies of the three types of atoms and

Accepted Answer

Welcome back everybody. We are comparing three mono atomic gasses. We are comparing helium, argon and xenon, and we are asked to compare the average kinetic energies of all three of these gasses. If all three of these gasses are placed in the same container and isolated from the atmosphere, let's look at the formula for average kinetic energy. Our formula is three halves times the bolts, man, constant times the temperature. Now, since all of these gasses are placed in the same container, the temperature is going to be constant and the bolts. One constant is of course constant, meaning that this entire term is going to be constant for all three gasses, meaning that the average kinetic energy of all three gasses inside the same container is going to be equal corresponding to answer choice B.
