True or false. At a constant temperature, lighter sized gas particles move faster than heavier sized gas particles.
Homework Answers
True.
Explanation:
With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature.
Since all gases have the same average kinetic energy at the same temperature, lighter molecules move faster and heavier molecules move slower on average.
