Question

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.

Answer 1

2)The particles in a liquid are moving past one another constantly.
3)The particles in gas move freely in all directions.
4)The particles in a solid vibrate in a fixed position.
6)The particles in a gas have few attractions between them.
7)The particles in all states of matter are always moving.

Answer 2

Answer: 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.
