• The energy released during a nuclear reaction.

Multiple Choice

Which of the following statements best describes what happens to the energy of particles at high and low temperatures according to the Kinetic Molecular Theory?

• At high temperatures, particles have high energy; at low temperatures, particles have less energy.

• At high temperatures, particles stop moving; at low temperatures, particles move faster.

• At high temperatures, particles lose energy; at low temperatures, particles gain energy.

• At high temperatures, particles are tightly packed; at low temperatures, particles spread out.

Multiple Select

Which of the following factors does thermal energy depend on?

• The type of particles in the system

• The total number of particles in the system

• How fast the particles are moving (their temperature)

• The color of the particles

Multiple Choice

How does the energy of particles differ between liquids, gases, and plasmas?

• Liquids have the most energy, followed by gases, then plasmas.

• Gases have the most energy, followed by plasmas, then liquids.

• Plasmas have the most energy, followed by gases, then liquids.

• Liquids and gases have the same energy, but plasmas have more.
