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 question is the experiment designed to investigate?
A.
Does the temperature of water change over time?
B.
Does the type of matter affect the transfer of energy?
C.
Does the foam cup insulate the heat energy of the water?
D.
Does the mass of the water influence the transfer of energy?
1 answer
The correct answer is:
B. Does the type of matter affect the transfer of energy?
This is because the experiment compares the thermal energy transfer between two different materials (the rock and the piece of metal) when placed in the same volume of heated water, allowing the student to investigate how different materials affect the interaction with thermal energy.
