Consider three 1.0-L flasks at STP. Flask A contains N₂ gas, flask B contains Kr gas, and flask C contains H₂ gas.In which flask do the gas particles have the lowest average kinetic energy?

Question

Quizplus · Accepted Answer

At STP (standard temperature and pressure), all gases have the same average kinetic energy according to the kinetic molecular theory. This is because the average kinetic energy of gas particles is directly proportional to the temperature, and since all flasks are at the same temperature, their gases have the same average kinetic energy regardless of the gas type.
