Consider three 10g samples of water: one as ice, one as a liquid, and one as a vapor. How does the volume of the vapor sample compare with the other?

Ok, first of all the vapor takes the largest volume of the three, the second is the ice (water is the only substance that in the solid form takes more volume than in the liquid one, that's why if you put a glass bottle filled with water into the freezer, the water will solidify and the bottle will break-try this!), the smallest volume is the liquid water
