Diatomic Gas

Molecule, is a collection of two or more atoms together (which constitute the smallest observable unit) into a pure material. There are some ways to represent the structure of a molecule. Factor symbols represent atoms in Lewis structures, and dots represent electrons that accompany them. A pair of mutual electrons (covalent bond) may be represented by a single dash. The ball-and-stick model depicts the spatial structure of the atoms better.

The average value of the squared speed does not equal the square of the average speed. To verify this fact, consider three particles with the following speeds; v1 = 1.76 m/s, v2 = 4.13 m/s, and v3 = 7.20 m/s. Calculate (a) the average value of the squared speed and (b) the square of the average speed.
