The average kinetic energy of water particles is directly related to the temperature of the water. The sample with the highest temperature will have the greatest average kinetic energy.
In the provided table, the temperatures of the samples are as follows:
- Sample 1: 15ºC
- Sample 2: 8ºC
- Sample 3: 22ºC
- Sample 4: 4ºC
Sample 3 has the highest temperature at 22ºC, indicating that it has water particles with the greatest average kinetic energy.
Therefore, the correct response is:
3
