A student uses a thermometer to record the temperature of several water samples as shown in the data table and image below. Other than the temperature, the water samples are the same. Which water sample below has the LOWEST kinetic energy?



-Water Sample 1 = 98.2 degrees C
-Water Sample 2 = 46 degrees C
-Water Sample 3 = 100.6 degrees C
-Water Sample 4 = 31.4 degrees C(1 point)
Responses

Water sample 1 at 98.2 °C has the lowest kinetic energy.

Water sample 2 at 46.0 °C has the lowest kinetic energy.

Water sample 3 at 100.6 °C has the lowest kinetic energy.

Water sample 4 at 31.4 °C has the lowest kinetic energy

1 answer

Kinetic energy in a substance is related to the temperature: the lower the temperature, the lower the kinetic energy of the molecules. Among the given water samples, Water Sample 4 at 31.4 °C has the lowest temperature, and therefore it has the lowest kinetic energy.

The correct response is: Water sample 4 at 31.4 °C has the lowest kinetic energy.
