 Celsius vs. Kelvin
Melting/Freeezing and Boiling/Condensing Points of Water
     Celsius
  Kelvin
  Melting/freezing point of water
  O°C
   273K
  Boiling/condensing point of water
  100°C
   373K
    • Lord Kelvin said that at 0°C there’s still some motion among the water molecules. Only at ABSOLUTE ZERO (0 K) is there no energy or movement.

You must memorize the melting/freezing point and boiling/condensing points of water above. The other elements’ melting/freezing points and boiling/condensing points are listed on Reffy.
(We’ll learn that later.)
