Which of the following is NOT an assumption of the kinetic theory of gases?

Question

A.
Gas particles are in constant random motion.

B.
The volume of individual gas particles is zero.

C.
The particles in a gas are attracted to each other.

D.
Gas particles collide without losing energy.

Answer 1

C. The particles in a gas are attracted to each other.

This is NOT an assumption of the kinetic theory of gases. The kinetic theory assumes that gas particles do not exert any forces on each other, which means there are no attractive or repulsive forces between them.
