Consider three 1-L flasks at the same temperature and pressure. Flask A contains CO gas, flask B contains N₂ gas, and flask C contains O₂ gas.In which flask do the molecules have the greatest kinetic energy?

Question

Quizplus · Accepted Answer

The kinetic energy of a gas molecule is related to its temperature, but not its identity. Since all three flasks are at the same temperature, the molecules in all of them have the same kinetic energy. Therefore, the correct answer is D, "The molecules in all the flasks have the same kinetic energy."
