During science class, Sophie measures the temperature of water every minute as it is heating. After a few minutes, the temperature increases to 82 °C. Which other property of the particles increases?

• mass

• volume

• average kinetic energy

• average potential energy

A student is using a thermometer to study a sample of matter. Which property of matter is the student measuring?

• mass

• density

• volume

• temperature

A ball rolls across the grass and eventually comes to a stop. What causes the ball to stop rolling?

• Thermal energy is created.

• Potential energy is created.

• The ball's motion energy is destroyed.

• The ball's motion energy is transformed.

Which of these best explains how temperature is related to heat?

• Temperature is a measure of the heat of an object.

• Heat causes a change in the temperature of an object.

• Raising the temperature causes the heat of an object to increase.

• Temperature and heat are two different ways to measure the same thing.

The tool in the figure shows the temperature on both the Fahrenheit scale and the Celsius scale.

What temperature does the tool show on the Fahrenheit scale?

• 70 °F

• 75 °F

• 80 °F

• 85 °F

Which type of energy is defined as the energy stored in the bonds of substances?

• light

• thermal

• chemical

• electrical

Laith notices that the air in his science classroom is much warmer than the air in his math classroom. Which statement describes how the air particles are different in his colder math classroom?

• They are vibrating.

• They move more freely.

• They move faster on average.

• They have less average energy.

Eduardo puts a beaker of ice and water on a hot plate as shown. After a few minutes, only liquid water is in the beaker. Eventually, the water boils.

How is thermal energy being transferred in this scenario?

• radiation

• convection

• conduction

• all of the above

Object A and object B are made of the same material. They are at the same temperature. They also contain the same amount of thermal energy. Which statement is true about objects A and B?

• Object A is larger than object B.

• Object B is larger than object A.

• Both objects are identical in size.

• There is not enough information to determine their size.
