Item AM036003: Water spilled on the floor will eventually disappear because the water molecules become a gas and are now part of the air.

You spill a little water on a tile floor but don’t have time to wipe it up. A few hours later, most of the water is gone. What happened to the water?

  1. The water molecules were destroyed.
  2. The water molecules got smaller and now take up less space.
  3. The water molecules became a gas and are now part of the air.
  4. The water molecules broke down into hydrogen and oxygen atoms, which are now in the air.
