HS-PS1-3 Review

What happens to the temperature of a liquid when it is heated (when energy is added)?

• It increases

• It decreases

• It stays the same

What happens to the temperature of a liquid when it is boiling?

• It increases

• It decreases

• It stays the same

When a substance remains in one state (solid, liquid, or gas) and heat is added (energy added), what happens to the temperature?

• It increases

• It decreases

• It stays the same

When a substance is changing states (solid -> liquid) and heat is added, what happens to the temperature of the substance?

• It increases

• It decreases

• It stays the same

When heat is taken away from a liquid (energy removed), but it stays a liquid, what happens to the temperature?

• It increases

• It decreases

• It stays the same

Describe what is happening at each point in the graph (A, B, C, D, and E)

Why does the temperature of a substance not increase when it is changing states?

• Intermolecular forces are being broken
• The substance is not capable of changing states
• The temperature is too low to cause a change in state
• The substance is not affected by temperature changes

If substance A changed from solid to liquid, which substance has a higher boiling point?

• Substance A

• Water

• Same boiling point

• Unable to tell from the graph

If substance A has changed from liquid to gas, which has the higher boiling point?

• Substance A

• Water

• Same boiling point

• Unable to tell from the graph

If substance A has changed from solid to liquid, which has the strongest force between particles?

• Substance A

• Water

• The same force

• Unable to tell from the graph
