There is also the peritectoid, a point where two solid phases combine into one solid phase during cooling. The inverse of this, when one solid phase transforms into two solid phases during cooling, is called the eutectoid. A complex phase diagram of great technological importance is that of the iron–carbon system for less than 7% carbon (see ...
In order to achieve temperatures lower than liquid helium at atmospheric pressure, additional cooler stages may be added to the cryostat. Temperatures down to 1 K can be reached by attaching the cold plate to a 1-K pot, which is a container of the He-4 isotope that may be pumped to low vapor pressure via a vacuum pump. Temperatures just below 0 ...
The heat necessary for the dilution is the useful cooling power of the refrigerator, as the process of moving the 3 He through the phase boundary is endothermic and removes heat from the mixing chamber environment. The 3 He then leaves the mixing chamber in the dilute phase. On the dilute side and in the still the 3 He flows through superfluid ...
Phase-change cooling is an extremely effective way to cool the processor. A vapor compression phase-change cooler is a unit that usually sits underneath the PC, with a tube leading to the processor. Inside the unit is a compressor of the same type as in an air conditioner. The compressor compresses a gas (or mixture of gases) which comes from ...
In the physical sciences, a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable. In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water.

In physics, the terms order and disorder designate the presence or absence of some symmetry or correlation in a many-particle system. [citation needed]In condensed matter physics, systems typically are ordered at low temperatures; upon heating, they undergo one or several phase transitions into less ordered states.
