The kinetic energy of water particles is directly proportional to the temperature. Therefore, the sample with the greatest temperature will have water particles with the greatest average kinetic energy.
By comparing the temperatures in each sample, we can see that:
Sample 1: 15oC
Sample 2: 8oC
Sample 3: 22oC
Sample 4: 4oC
Therefore, sample 3 has the greatest temperature and therefore the greatest average kinetic energy. So the answer is 3.
