Question

Which statement about the kinetic molecular theory of gases is false?

A: Molecules are in constant random motion
B: Size is important
C: Forces between molecules are weak
D: Collisions are perfectly elastic
E: None of the above

Answer 1

The false statement regarding the kinetic molecular theory of gases is B: Size is important as the theory considers gas particles as points with negligible volume.

Step-by-step explanation:

Among the statements presented about the kinetic molecular theory of gases, the false one is B: Size is important. This goes against one of the core assumptions content loaded with the theory which posits that gas particles are considered to be points of negligible volume.

Other assumptions include:

Molecules are in constant random motion.Forces between molecules are weak meaning no intermolecular forces are present.Collisions are perfectly elastic conserving energy during collisions.

The average kinetic energy of the particles is dependent only on the temperature of the gas.

Therefore, the correct statement about the kinetic molecular theory that is false is one that attributes importance to the size of gas molecules.
