Unit 2 Review

How are temperature and thermal energy related?

• The higher the temperature, the higher the thermal energy
• The lower the temperature, the higher the thermal energy
• They are not related
• They have an inverse relationship

When something goes from a solid to a gas (without going through the liquid phase), it is called _______

• Sublimation
• Deposition
• Melting
• Freezing

When something goes from a liquid to a gas, it is called _______

• Vaporization
• Condensation
• Freezing
• Sublimation

It takes 30 mL of water longer to boil than 15 mL of water under the same heating source. How do their boiling points compare?

• 30 mL has a higher BP
• 15 mL has a higher BP
• Depends on the day
• They are the same

In the phase change diagram, temperature does not change during a phase change. What is the explanation for this?

• There is no change in heat energy
• Phase changes require ALL available heat energy
• Heat energy is transferred to another experiment
• Magic

What contains the least amount of energy?

• Hot water
• Steam

The relationship between density and volume of an object is an inverse relationship. This means that as the volume of an object increases, the density:

• Increases
• Decreases
• Stays the same
• Is not related to the volume

The formula for density is: 

• D=M/V
• D=V/M
• D=MA
• D=MC^2

The amount of matter that an object has is known as its

• Mass
• Volume
• Weight
• Density

Volume is measured in

• mL
• cc
• L
• All of the options
