Which of the following molecules/atoms will exert a greater force when it strikes the wall of the container under ideal conditions?

Question

Quizplus · Accepted Answer

Under ideal conditions, all gases at the same temperature have the same average kinetic energy. The force exerted when a molecule or atom strikes the wall of a container depends on its momentum change upon collision. Since all options have different temperatures, we compare based on the kinetic energy and mass. Helium atoms at 1500 K will have more kinetic energy due to the higher temperature, and being lighter, they will have higher velocities, leading to a greater force upon collision compared to the other options.
