Energy and Heat

How does the temperature of the water in the large beaker compare or contrast with the temperature of the water in the small beaker?

• The water in the small beaker has a greater temperature than the water in the large beaker because the water in the small beaker has less mass.

• The water in the large beaker has a greater temperature than the water in the small beaker because the water in the large beaker has more thermal energy.

• The water in the large beaker and the water in the small beaker have the same temperature because the thermometers show the same readings.

• The water in the large beaker has a greater temperature than the water in the large beaker does not cool as quickly when heated.

The temperature in a beaker of water is 50 °C. Kiley puts the water into a freezer. After a few minutes, she measures the temperature again. It is now 10 °C. How did the water particles change?

• They moved more freely.

• They moved closer together.

• The average speed increased.

• The average kinetic energy increased.

As part of a lab experiment, Tasha drops a metal cube into a beaker of water, as shown in the figure below. After energy in the form of heat transfers between the substances, what is the final temperature of the water?

• The final temperature is 25 °C because there is more water than metal.

• The final temperature is 50 °C because the metal warms the water to the temperature of the metal.

• The final temperature is between 25 °C and 50 °C because energy is transferred from the metal to the water.

• The final temperature is between 25 °C and 50 °C because most of the thermal energy is lost to the air around the substances.
