Heat vs 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.
