The average kinetic energy of water molecules is directly related to temperature. Higher temperatures correspond to greater average kinetic energy.
From the given temperatures:
- Sample L: 40ºC
- Sample M: 88ºC
- Sample N: 21ºC
Ordering these from greatest to least average kinetic energy (or temperature):
- M (88ºC)
- L (40ºC)
- N (21ºC)
So the correct order from greatest to least is: M, L, N.
The correct response is: M, L, N
