6th Science Lesson 4-1 Review

What is another name for thermal energy?

• Kinetic energy
• Internal energy
• Potential energy
• Temperature

When does heat stop being transferred between two objects?

• When the particles are rearranged
• When the heat rises
• When the objects reach the same temperature
• When the temperature reaches absolute zero

What happens to particles at a temperature of absolute zero?

• The particles gain more kinetic energy.
• The particles lose potential energy.
• The particles are rearranged.
• The particles have no kinetic energy.

Which factors DO NOT contribute to a substance’s thermal energy?

• Arrangement of particles
• State of matter
• Amount of matter
• The color of the substance

Two substances that have the same temperature will have the same thermal energy.

• True
• False

When an object changes states, the thermal energy changes but the temperature stays the same.

• True
• False

Heating a substance can cause its particles to move more slowly.

• True
• False

If two objects have the same amount of matter, which object has more thermal energy?

• The object that is solid has more thermal energy.
• The object that transfers electrical energy to thermal energy has more thermal energy.
• The object with the highest temperature has more thermal energy.
• The object that has a greater gravitational pull has more thermal energy.
