Kinetic Theory of Liquids

Particles are loosely packed. Can change position - has a definite volume, but takes the shape of its container.

• Bose-Einstein Condensate

• Solid

• Liquid

• Gas

• Plasma

Which of the following best describes the kinetic theory of liquids?

• Particles are in fixed positions and vibrate in place.

• Particles move freely and fill the entire container.

• Particles are closely packed but can move past one another.

• Particles are ionized and conduct electricity.

What happens to the particles in a liquid when it is heated?

• They move slower and get closer together.

• They move faster and spread apart.

• They stop moving entirely.

• They form a solid structure.

According to the kinetic theory, what is the main difference between the particles in a liquid and a gas?

• Particles in a liquid are more energetic than in a gas.

• Particles in a liquid are less energetic and more closely packed than in a gas.

• Particles in a liquid are more spread out than in a gas.

• Particles in a liquid are ionized while in a gas they are not.

How does pressure affect the particles in a liquid according to the kinetic theory?

• Increased pressure makes particles move faster.

• Increased pressure makes particles move slower.

• Increased pressure has no effect on particle movement.

• Increased pressure causes particles to ionize.
