Use the equation to answer the question. H2O(l) + heat ⇄ H2O(g)
A sample of water is at equilibrium at 100°C. Which statement best describes what will happen if liquid water is added to the system?

-More liquid water molecules will change to water vapor until a new equilibrium is reached.
-All of the liquid water molecules that are added will become water vapor.
-More water vapor molecules will change to liquid water until a new equilibrium is reached.
-All of the liquid water molecules that are added will remain liquid water.
