What would happen to a sample of water at

30˚ C. If it is heated until the temperature

reaches 120˚C?

Main Idea

As temperature increased, the water

would expand and more water would

evaporate. At 100˚C (212˚F), the water

would boil into gaseous water.

Beyond 100˚C, all of the water would

be a gas that would keep expanding.
