Answer 1

The average kinetic energy of water molecules is directly related to the temperature of the samples. The higher the temperature, the greater the average kinetic energy.

From the table:

• Sample L: 40ºC
• Sample M: 88ºC
• Sample N: 21ºC

To order the samples from greatest to least average kinetic energy, we arrange them by temperature:

1. Sample M (88ºC) - greatest average kinetic energy
2. Sample L (40ºC)
3. Sample N (21ºC) - least average kinetic energy

Thus, the correct order is:

M, L, N.
