Question

Which of the following does not follow the kinetic molecular theory?

Gas molecules have negligible volume.

Gas molecules do not have mass.

The average kinetic energy of gas molecules is proportional to the temperature of the gas molecules.

Gas molecules possess no attraction or repulsion to one another.

Answer 1

Gas molecules do not have mass, because all of the other choices follow the kinetic molecular theory

Answer 2

Speaking of Kinetic Molecular Theory, this theory states that the gas molecules in a container possesses motion that is constant and the kinetic energy of these molecules is dependent on the temperature of the gas. Therefore, on the given statements above, the one that does not follow this theory is the last option.
