What is unusual about the phase diagram for water?
Well, it's one way the water phase diagram is different. Water has a unique structure that makes the liquid denser than the solid. Density is how much mass is in a certain volume.
What is triple point phase diagram of water?
Triple point is the intersection on a phase diagram where three phases coexist in equilibrium. The most important application of triple point is water, where the three-phase equilibrium point consists of ice, liquid, and vapor.
What is water in its normal phase?
Water occurs as a liquid on the surface of Earth under normal conditions, which makes it invaluable for transportation, for recreation, and as a habitat for a myriad of plants and animals. The fact that water is readily changed to a vapour (gas) allows it to be transported through the atmosphere from the oceans to inland areas where it condenses and, as rain , nourishes plant and animal life.
