Heat and Temperature

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.

How does the thermal energy of the liquid in the larger beaker compare to the thermal energy of the liquid in the smaller beaker?

• The liquid in the larger beaker has less thermal energy than the liquid in the smaller beaker.

• The liquid in the larger beaker has more thermal energy than the liquid in the smaller beaker.

• The liquid in the larger beaker has the same amount of thermal energy as the liquid in the smaller beaker.

• The exact volume of the liquid in each beaker must be known to compare the thermal energy of the liquids.
