The root mean square speed of a gas molecule is greater than the average speed, because the former gives a greater weight to
A) lighter molecules.
B) heavier molecules.
C) lower speeds.
D) higher speeds.
E) more probable speeds.

Question

Quizplus · Accepted Answer

The root mean square speed equation takes into account all speeds of gas molecules, including the higher speeds. This means that the higher speeds have a greater weight in the calculation of the root mean square speed, leading to a higher value compared to the average speed.
