The image below represents which of the following (check all that apply): one atom one element mixture molecule compound pure substance

ANSWERS

Compound

Molecule

Pure substance

As temperature increases, the molecules and atoms move faster.

According to the Kinetic Molecular Theory of gases, the average kinetic energy (KE) of the molecules is proportional to the Kelvin temperature.

KE = ½ mv²

Thus, if T increases, KE increases and so does the speed (v) of the particles.
