A molecule of nitrogen exerts more pressure than a molecule of oxygen because nitrogen is a larger molecule.

Question

Quizplus · Accepted Answer

The size of a molecule is not the only factor in its pressure. Pressure is determined by the number of molecules present and their average kinetic energy, which is related to their temperature. Oxygen and nitrogen molecules have similar sizes and therefore exert similar pressures at the same temperature and pressure.
