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.
The water in Mario’s swimming pool absorbs energy as heat during the day. Which of the following would the water in the pool be most likely to do?
condense
evaporate
freeze
melt

Emerson places a beaker of water on a hotplate and turns the hotplate on. The temperature in the room is 25 ºC. After the water heats to 75 ºC, she adds pieces of ice to the beaker.
Which of the following describes a transfer of heat energy that occurs during this experiment?
from the air to the water
from the ice to the beaker
from the water to the ice
from the water to the hotplate

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.
Which description defines heat?
total thermal energy of an object or substance
change in the temperature of a substance in degrees Celsius
energy transferred between objects at different temperatures
average kinetic energy of the particles that make up a substance
