What happens to the kinetic energy of particles in a substance when heat (thermal energy) is added?

• Kinetic Energy Increases
• Kinetic Energy Decreases
• Kinetic Energy Remains Constant

The more lines drawn on a particle, the faster the particle is moving.

• True
• False

For the following question select all answers that apply: When kinetic energy is added to a substance what happens to the particles?

• The particles slow down
• The particles speed up
• The particles spread out
• The particles get closer together
• Nothing happens to the particles

If a material has a higher temperature, it means that it has more kinetic energy than a material will less temperature.

• True
• False

For the following question select all that apply: In a gas, the particles

• move at high speeds
• have high amounts of kinetic energy
• are spread out and move freely
• are always moving
• move at moderate speeds

For the following question select all that apply: In a liquid, the particles

• move at moderate speeds
• have a moderate amount of kinetic energy
• are close together, but can still move freely
• are always moving
• move at high speeds

For the following question select all that apply: In a solid, the particles

• move at slow speeds
• have a low amount of kinetic energy
• are compact in a rigid structure, particles still move, but not freely
• are always moving
• move at high speeds
