Answer 1

The average kinetic energy of water molecules is directly related to the temperature of the water samples. In this case, the temperatures are as follows:

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

To order the samples from greatest to least average kinetic energy, we should rank the temperatures from highest to lowest:

1. M (88 ºC) - Greatest average kinetic energy
2. L (40 ºC)
3. N (21 ºC) - Least average kinetic energy

So the correct order from greatest to least average kinetic energy of the water molecules is:

M, L, N

The correct response is: M, L, N.
