A student fills 3 glasses with different amounts of water as shown. What happens to the size of the water molecules with a change in water volume?
Water molecules in glass 1 would be larger because it has the greatest volume.
Water molecules in glass 2 are twice as large as glass 3 because glass 2 has twice as much water as glass 3.
Water molecules are the same size in each glass, because the amount of water does not affect the molecules' size.
