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.
The student plans to compare the results from each part of the investigation.
Multiple Choice Question
Which of the following questions will the experiment help to answer?
A.
What causes the mass of water to change over time?
B.
How can different materials change the boiling point of water?
C.
Can different types of matter take up the same amount of volume?
D.
Does water transfer the same amount of energy to different types of matter?
1 answer
The correct answer is:
D. Does water transfer the same amount of energy to different types of matter?
The experiment involves measuring how the temperature of water changes when different materials (the rock and the piece of metal) are added to it. This allows the student to compare how much thermal energy is transferred to each material, which directly relates to how different types of matter absorb energy from water.
