Energy and Heat Practice Tests

These Grade 7 Science practice tests build understanding of kinetic and potential energy, thermal energy, heat, temperature, conduction, convection, radiation, insulation, energy transformations, and conservation.

Skills covered

  • Distinguishing kinetic, potential, chemical, thermal, electrical, light, and sound energy
  • Explaining the difference between heat, temperature, and total thermal energy
  • Identifying conduction, convection, radiation, and insulation in real situations
  • Tracking energy transfers and transformations in systems
  • Applying conservation of energy to machines, motion, heating, and everyday technology

How to use these practice tests

For each question, identify the system and the energy form involved. Then trace where energy moves or changes and decide whether the evidence describes heat transfer, temperature, or energy conservation.

1. QuestionMultiple choice

What is heat?

Please select an answer first.

Correct answer: A

The correct answer is The transfer of thermal energy from a warmer object to a cooler object.

  1. Identify the energy idea: Determine whether the question concerns energy form, energy transfer, heat, temperature, or an energy system.
  2. Connect the evidence: Heat is energy in transit because of a temperature difference.
  3. Check conservation: Energy can move or change form, but a complete system accounts for the energy rather than treating it as created or destroyed.

Heat is energy in transit because of a temperature difference.

2. QuestionMultiple choice

What does temperature measure?

Please select an answer first.

Correct answer: B

The correct answer is The average kinetic energy of particles in a substance.

  1. Identify the energy idea: Determine whether the question concerns energy form, energy transfer, heat, temperature, or an energy system.
  2. Connect the evidence: Temperature indicates the average particle motion, while thermal energy also depends on the amount of matter.
  3. Check conservation: Energy can move or change form, but a complete system accounts for the energy rather than treating it as created or destroyed.

Temperature indicates the average particle motion, while thermal energy also depends on the amount of matter.

3. QuestionMultiple choice

Why can a large warm tub contain more thermal energy than a small hot cup?

Please select an answer first.

Correct answer: C

The correct answer is The tub contains many more particles, so its total thermal energy can be greater..

  1. Identify the energy idea: Determine whether the question concerns energy form, energy transfer, heat, temperature, or an energy system.
  2. Connect the evidence: Total thermal energy depends on particle motion and the amount of matter, not temperature alone.
  3. Check conservation: Energy can move or change form, but a complete system accounts for the energy rather than treating it as created or destroyed.

Total thermal energy depends on particle motion and the amount of matter, not temperature alone.

4. QuestionMultiple choice

In which direction does heat naturally transfer?

Please select an answer first.

Correct answer: D

The correct answer is From a warmer object to a cooler object.

  1. Identify the energy idea: Determine whether the question concerns energy form, energy transfer, heat, temperature, or an energy system.
  2. Connect the evidence: Thermal energy moves down a temperature gradient until the objects approach thermal equilibrium.
  3. Check conservation: Energy can move or change form, but a complete system accounts for the energy rather than treating it as created or destroyed.

Thermal energy moves down a temperature gradient until the objects approach thermal equilibrium.

5. QuestionMultiple choice

What is thermal equilibrium?

Please select an answer first.

Correct answer: A

The correct answer is A condition in which objects in contact reach the same temperature and have no net heat transfer..

  1. Identify the energy idea: Determine whether the question concerns energy form, energy transfer, heat, temperature, or an energy system.
  2. Connect the evidence: When temperatures are equal, there is no overall transfer of heat between the objects.
  3. Check conservation: Energy can move or change form, but a complete system accounts for the energy rather than treating it as created or destroyed.

When temperatures are equal, there is no overall transfer of heat between the objects.

6. QuestionMultiple choice

Why does a metal spoon in hot soup become warm?

Please select an answer first.

Correct answer: B

The correct answer is Thermal energy transfers from the soup through the spoon..

  1. Identify the energy idea: Determine whether the question concerns energy form, energy transfer, heat, temperature, or an energy system.
  2. Connect the evidence: The temperature difference causes thermal energy to move from the hot soup into the cooler spoon.
  3. Check conservation: Energy can move or change form, but a complete system accounts for the energy rather than treating it as created or destroyed.

The temperature difference causes thermal energy to move from the hot soup into the cooler spoon.

7. QuestionMultiple choice

What usually happens when a substance is heated?

Please select an answer first.

Correct answer: C

The correct answer is Its particles gain kinetic energy and may move faster or change arrangement..

  1. Identify the energy idea: Determine whether the question concerns energy form, energy transfer, heat, temperature, or an energy system.
  2. Connect the evidence: Heating adds thermal energy, increasing particle motion and sometimes causing a phase change.
  3. Check conservation: Energy can move or change form, but a complete system accounts for the energy rather than treating it as created or destroyed.

Heating adds thermal energy, increasing particle motion and sometimes causing a phase change.

8. QuestionMultiple choice

Why does a cold metal railing feel colder than a wooden railing at the same temperature?

Please select an answer first.

Correct answer: D

The correct answer is Metal transfers thermal energy away from your hand more quickly..

  1. Identify the energy idea: Determine whether the question concerns energy form, energy transfer, heat, temperature, or an energy system.
  2. Connect the evidence: Metal is a better thermal conductor, so it draws energy from your hand more rapidly.
  3. Check conservation: Energy can move or change form, but a complete system accounts for the energy rather than treating it as created or destroyed.

Metal is a better thermal conductor, so it draws energy from your hand more rapidly.

9. QuestionMultiple choice

What is the difference between heat and temperature?

Please select an answer first.

Correct answer: A

The correct answer is Heat is transferred thermal energy, while temperature measures average particle kinetic energy..

  1. Identify the energy idea: Determine whether the question concerns energy form, energy transfer, heat, temperature, or an energy system.
  2. Connect the evidence: Temperature describes a state; heat describes energy moving because of a temperature difference.
  3. Check conservation: Energy can move or change form, but a complete system accounts for the energy rather than treating it as created or destroyed.

Temperature describes a state; heat describes energy moving because of a temperature difference.

10. QuestionMultiple choice

Why does adding the same amount of energy affect a small sample more quickly?

Please select an answer first.

Correct answer: B

The correct answer is The energy is distributed among fewer particles..

  1. Identify the energy idea: Determine whether the question concerns energy form, energy transfer, heat, temperature, or an energy system.
  2. Connect the evidence: With fewer particles sharing the transferred energy, the average particle energy and temperature can change more.
  3. Check conservation: Energy can move or change form, but a complete system accounts for the energy rather than treating it as created or destroyed.

With fewer particles sharing the transferred energy, the average particle energy and temperature can change more.
