Answer 1

The temperature of a substance is directly related to the average kinetic energy of its molecules. In this case, the water sample that has the lowest temperature will also have the lowest kinetic energy.

From the table:

• Sample 1: 98.2 °C
• Sample 2: 46.0 °C
• Sample 3: 100.6 °C
• Sample 4: 31.4 °C

Sample 4 has the lowest temperature at 31.4 °C. Therefore, it has the lowest kinetic energy.

The correct response is 4.
