High School

A teacher put 15 mL of saltwater and a thermometer into each of four beakers. She placed the beakers in different locations around her classroom. The next day, students recorded the temperature of the liquid in each beaker.

In which beaker was the average kinetic energy of the particles greatest?

A. Beaker A: 3°C
B. Beaker B: 9°C
C. Beaker C: 15°C
D. Beaker D: 18°C

Answer :

Final answer:

Beaker D, which has a temperature of 18°C, has the highest average kinetic energy of particles because the average kinetic energy is directly related to temperature.

Explanation:

The beaker with the greatest average kinetic energy of the particles would be Beaker D, which has a temperature of 18°C. The average kinetic energy of particles in any substance is directly proportional to its temperature. This means that when the temperature is higher, the average kinetic energy is also higher. Therefore, since Beaker D has the highest recorded temperature, the particles of saltwater in Beaker D would be moving faster and have greater kinetic energy than in the other beakers.
