At a certain temperature, the speeds of six gaseous molecules in a container are 2.0 m s-1, 2.2 m s-1, 2.6 m s-1, 2.7 m s-1, 3.3 m s-1, and 3.5 m s-1. Calculate the root-mean-square speed and the average speed of the molecules. These two average values are close to each other, but the root-mean-square value is always the larger of the two. Why
