Kinetic Molecular Theory Quiz

What does the Kinetic Molecular Theory state about particles?

• Particles are static and unchanging.

• Particles are always in motion.

• Particles do not exist in gases.

• Particles are visible to the naked eye.

What happens to particles in a solid state like ice?

• They expand and fill the container.

• They do not move and stay in a fixed pattern.

• They are compressed into a smaller volume.

• They move freely and quickly.

How do particles in a liquid state behave?

• They expand infinitely.

• They are tightly packed and hardly move.

• They move around with moderate freedom.

• They are completely static.

What is a characteristic of gas particles?

• They form a regular pattern.

• They can be compressed and are usually invisible.

• They are visible and tightly packed.

• They are always condensed.

How does temperature affect the energy of particles?

• Higher temperature reduces particle energy.

• Higher temperature increases particle energy.

• Temperature has no effect on particle energy.

• Lower temperature increases particle energy.

What does the Kinetic Molecular Theory explain?

• The behavior of particles in various states of matter

• The structure of atomic nuclei

• The process of chemical reactions

• The laws of thermodynamics

According to the Kinetic Molecular Theory, particles in matter are always: (a)  

• Moving
• At rest
• Non-existent
• In a fixed position

What happens to the particles when the temperature is increased?

• They move faster

• They become larger

• They bond together

• They change state

In which state of matter do particles have the most energy?

• Plasma

• Liquid

• Solid

• Gas

What is a characteristic of particles in a solid state like ice?

• They expand indefinitely

• They are loosely packed

• They move freely and quickly

• They hardly move and hold a regular pattern
