1. QuestionMultiple choice

What does a balanced chemical equation show?

Please select an answer first.

Correct answer: A

The correct answer is The same number of each type of atom appears on both sides.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: A balanced equation represents conservation of atoms by showing equal numbers of each element before and after the reaction.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

A balanced equation represents conservation of atoms by showing equal numbers of each element before and after the reaction.

2. QuestionMultiple choice

What occurs in an endothermic process?

Please select an answer first.

Correct answer: B

The correct answer is Energy is absorbed from the surroundings.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: An endothermic process absorbs energy, often causing the surroundings to cool.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

An endothermic process absorbs energy, often causing the surroundings to cool.

3. QuestionMultiple choice

A solution has a pH of 3. Which statement is correct?

Please select an answer first.

Correct answer: C

The correct answer is It is acidic.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Values below 7 on the pH scale are acidic, while 7 is neutral and values above 7 are basic.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Values below 7 on the pH scale are acidic, while 7 is neutral and values above 7 are basic.

4. QuestionMultiple choice

Two objects have the same mass. Which object has greater acceleration when acted on by a greater net force?

Please select an answer first.

Correct answer: D

The correct answer is The object experiencing the greater net force.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: For the same mass, Newton second law predicts that greater net force produces greater acceleration.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

For the same mass, Newton second law predicts that greater net force produces greater acceleration.

5. QuestionMultiple choice

What happens to momentum when the mass of a moving object increases while its velocity stays the same?

Please select an answer first.

Correct answer: A

The correct answer is Its momentum increases.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Momentum depends on mass and velocity, so greater mass at the same velocity produces greater momentum.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Momentum depends on mass and velocity, so greater mass at the same velocity produces greater momentum.

6. QuestionMultiple choice

A roller coaster moves from a high hill to a low point with little friction. What energy transformation occurs?

Please select an answer first.

Correct answer: B

The correct answer is Gravitational potential energy changes into kinetic energy.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: As height decreases, gravitational potential energy is transferred into kinetic energy of motion.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

As height decreases, gravitational potential energy is transferred into kinetic energy of motion.

7. QuestionMultiple choice

For the same voltage, what happens to current when resistance increases?

Please select an answer first.

Correct answer: C

The correct answer is Current decreases.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Ohm law describes an inverse relationship between current and resistance when voltage is held constant.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Ohm law describes an inverse relationship between current and resistance when voltage is held constant.

8. QuestionMultiple choice

If wave speed stays constant, what happens to wavelength when frequency increases?

Please select an answer first.

Correct answer: D

The correct answer is Wavelength decreases.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Wave speed equals frequency times wavelength, so higher frequency requires shorter wavelength when speed is constant.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Wave speed equals frequency times wavelength, so higher frequency requires shorter wavelength when speed is constant.

9. QuestionMultiple choice

Why can a gas be compressed more easily than a liquid?

Please select an answer first.

Correct answer: A

The correct answer is Gas particles have much more space between them.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: The large spaces between gas particles can be reduced, while liquid particles are already close together.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

The large spaces between gas particles can be reduced, while liquid particles are already close together.

10. QuestionMultiple choice

What distinguishes a nuclear change from a typical chemical change?

Please select an answer first.

Correct answer: B

The correct answer is A nuclear change involves the atomic nucleus.

  1. Identify the evidence: Read the model, data, equation, or system described in the question.
  2. Apply the science idea: Nuclear changes involve the nucleus and can release much more energy than ordinary chemical changes.
  3. Check the conclusion: Confirm that the answer is consistent with the evidence and the Grade 10 science concept.

Nuclear changes involve the nucleus and can release much more energy than ordinary chemical changes.
