Which of the following gas molecules have the highest average kinetic energy at 25°C? A) H₂ B) O₂ C) N₂ D) Cl₂ E) All the gases have the same average kinetic energy.

Question

Quizplus · Accepted Answer

At a given temperature, all gases have the same average kinetic energy. This is known as the Kinetic Molecular Theory, which states that the average kinetic energy of a gas is proportional to its temperature in Kelvin. Therefore, the identity of the gas molecule does not affect its kinetic energy.
