heavier (larger) particles move faster than lighter (smaller) particles at the same temperature. true or false

Brief Explanations:

At the same temperature, the average kinetic - energy of particles is the same. Kinetic energy is given by $KE=\frac{1}{2}mv^{2}$. Heavier particles have a larger mass $m$, so to have the same $KE$, they must have a lower velocity $v$. Lighter particles have a smaller mass $m$ and thus a higher velocity $v$.

Answer:

False
