Which of the following are part of kinetic-molecular theory? check all that apply. the particles in a solid do not move. the particles in a liquid are moving past one another constantly. the particles in gas move freely in all directions. the particles in a solid vibrate in a fixed position. the particles in a solid are far apart. the particles in a gas have few attractions between them. the particles in all states of matter are always moving.

The correct answers are "The particles in gas move freely in all directions" and "The particles in a gas have few attractions between them".

Explanation:

Kinetic-molecular theory postulates are as follows;

--The molecules of the gas are small and far apart.

--They are in constant in the random motion.

--The molecules of the gases collide with each other. They also collide with the walls of the container.

-- There is perfectly elastic collision between the gas molecules as there is no loss of kinetic energy.

--They do not exert repulsive or attractive forces on one another except during collision.

Therefore, the following are the statements related to kinetic-molecular theory from the given option;

The particles in gas move freely in all directions.

The particles in a gas have few attractions between them.
