Which postulate of the kinetic-molecular theory applies to the particles of a liquid?
They do not move freely but vibrate in a stationary position.
They can be compressed, which causes a large change in volume.
They have so much kinetic energy that their intermolecular forces are negligible.
They have enough kinetic energy to easily slide by each other.

Respuesta :

Answer:

D) They have enough kinetic energy to easily slide by each other.

The particles of liquid have enough kinetic energy to easily slide by each other. The correct option is D.

What is kinetic-molecular theory?

The kinetic-molecular hypothesis stated matter states and is based on the assumption that matter is made up of tiny particulate that are constantly in motion.

This theory adds to the knowledge of observable properties and behaviors of solids, liquids, and gases.

Because they are densely packed and vibrate in place, solids have the lowest kinetic energy.

Since liquids have higher kinetic energy, the particles slide past each other. Because gases have the most kinetic energy, they float around in the air.

Particles in liquids are very close together and move randomly throughout the container.

Due to the shorter distances between particles, particles move rapidly in all orientations but strike with each other more frequently than in gases.

Thus, the correct option is D.
