Question

Use the table to answer the question. Sample Temperature (°C) 1 98.2 2 46.0 3 100.6 4 31.4 A student records the temperature of several water samples as shown in the table. Other than the temperature, the water samples are the same. Which sample has the lowest kinetic energy? (1 point) Responses 3 3 1 1 2 2 4

Answer 1

Kinetic energy of molecules is related to their temperature; higher temperatures generally indicate higher kinetic energy. In the provided data:

• 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 (31.4 °C), which means it also has the lowest kinetic energy.

Therefore, the response is 4.
