Phase Diagrams a Review
The phase diagram of water is a common example. Water may stay in liquid solid or gaseous states in different pressure-temperature regions.

Water is Unusual The typical phase diagram The H 2O phase diagram Most materials freeze if you push hard enough but water melts! This results from the fact that water expands when it freezes (ice floats) Consequences: • Fish can live in wintry lakes because they don’t freeze solid • Ice is slippery when you skate on it GNOT!

The phase diagram for the water system is shown in Fig 6 1 The phase diagram consists of Curves : There are three curves OA OB and OC Areas : Three curves OA OB and OC divide the diagram into three areas AOB AOC and BOC Triple point : The above three curves meet at the point O and is known as triple point
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.
