Question

Quizplus · Accepted Answer

Helium, being a lighter element, would have a higher velocity at a given temperature compared to heavier molecules. As the temperature increases, the kinetic energy of helium atoms increases, making it more likely for them to escape the planet's gravitational pull compared to water, ionized oxygen, or ozone.
