The table shows the temperature of three water samples. Which list shows the samples in order from greatest to least average kinetic energy of the water molecules?
(1 point)
O M, L, N OL, M,N
O N, M, L O N, L, M

1 answer

The average kinetic energy of water molecules is related to their temperature: higher temperatures mean greater average kinetic energy.

From the table you provided:

  • Sample L: 40 °C
  • Sample M: 88 °C
  • Sample N: 21 °C

Ordering these from greatest to least average kinetic energy based on temperature gives us:

  1. M (88 °C)
  2. L (40 °C)
  3. N (21 °C)

Therefore, the correct order is M, L, N.
