Thermal Energy
A student plans to conduct an experiment using foam cups, some water, a rock, and a piece of metal
At first, the rock is placed on a scale, and its mass of 123 grams gets recorded. Then, 123 grams of water get heated on the
stove to 100°C. The water is poured into a foam cup, followed by the unheated rock. The temperature of the water is recorded
with a thermometer until the temperature appears to stabilize

In the second part of the experiment, water gets heated on the stove. The water gets poured into a foam cup, and then a
piece of metal is added. The temperature of the water is recorded with a thermometer until the temperature appears to
stabilize
Which of the following questions will the experiment help to answer?
OF
What causes the mass of water to change over time?
How can different materials change the boiling point of water?
e Can different types of matter take up the same amount of volume?
Does water transfer the same amount of energy to different types of matter?
