PHASE DIAGRAMS OF PURE SUBSTANCES - Main Menu

At its simplest, a phase can be just another term for solid, liquid or gas. If you have some ice floating in water, you have a solid phase present and a liquid phase. If there is air above the mixture, then that is another phase. But the term can be used more generally than this. For example, oil

Besides the stretched liquid water, guest-free clathrates can be regarded as low-density phases of water ice that exist in the negative-pressure region of the phase diagram (21, 22, 29, 30) and have been investigated by classical molecular dynamics (MD) simulations.

Phase Diagrams - Phases of Matter and Phase Transitions

A phase diagram is a graphical representation of pressure and temperature of a material. Phase diagrams show the state of matter at a given pressure and temperature. They show the boundaries between phases and the processes that occur when the pressure and/or temperature is changed to cross these boundaries.

Phase diagram - Wikipedia

For example, the water phase diagram has a triple point corresponding to the single temperature and pressure at which solid, liquid, and gaseous water can coexist in a stable equilibrium (273.16 K and a partial vapor pressure of 611.657 Pa).

phase diagrams for micellar systems - NIST

The phase diagram for the water-surfactant (A-C) binary solution is more complex and is characterized by a UCST behavior at low temperatures and a closed loop immiscibility island at high temperatures; i.e., it phase separates both upon cooling and

Phase Diagrams | Boundless Chemistry - Lumen Learning

Phase diagrams can be used to understand the range of thermodynamic variables over which a pure sample of matter exists as a particular state/phase. Phase diagrams are divided into three single phase regions that cover the pressure – temperature space over which the matter being evaluated exists: liquid, gaseous, and solid states.

Physics in the kitchen: The Magical Can Crusher

So, when you boiled the water in the can the atoms in the water moved around faster until they move so fast that they went through a phase change and changed from the liquid, water, to a gas called water vapor. Water vapor, which could be seen as steam escaping from the can, replaced the air that was originally in the can by pushing the air out of the can. The atoms in the water vapor moved ...

Collapsing Can Experiment - Bassam Shakhashiri

You can crush an open aluminum can with your hand. When you squeeze on the can, the pressure outside becomes greater than the pressure inside. If you squeeze hard enough the can collapses. Usually, the air pressure inside an open can is the same as the pressure outside. However, in this experiment, the air was driven out of the can and replaced by water vapor. When the water vapor …

Could someone explain the can crushing experiment? | …

2010-09-01· When you put the can into the cold water the sides of the can cool down rapidly, which allows the steam to condense on the sides of the can. This happens much too rapidly for the water to rush in through the mouth of the can and fill the space, so the pressure decreases inside the can and the external air pressure crushes the can."
