Students did an experiment with thermal energy. They put a metal spoon in the
freezer for a while. Next, they put hot water in a beaker and measured the water
temperature.
Experiment Data
Water temperature
43* C
How the spoon feels
Cold
Then they removed the spoon from the freezer and put it in the hot water. After 10 minutes, the students measures the water temperature again and touched the spoon. What changes do you predict the students will measure and feel? Base your predictions on the thermal energy of the water and the spoon.
Answers:
- The temperature goes down and the spoon feels colder because the water and the spoon both lost thermal energy.
- The Temperature goes up and the spoon feels colder because the water gained thermal energy and the spoon lost thermal energy.
-The temperature goes down and the spoon feels warmer because the water lost thermal energy and the spoon gained thermal energy.
- The temperature goes up and the spoon feels warmer because the water and the spoon both gained thermal energy.
