The average kinetic energy of water molecules is directly related to the temperature of the water. Higher temperatures indicate greater average kinetic energy.

From the table:

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

To rank these samples from greatest to least average kinetic energy based on their temperatures:

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

Thus, the correct order from greatest to least average kinetic energy is:

M, L, N
