Phase (maiter)

o matter
(Reguidit frae Phase (matter))

In the pheesical sciences, a phase is a region o space (a thermodynamic seestem), atouer whilk aw pheesical properties o a material is essentially uniform.[1] Insaumples o pheesical properties include density, index o refraction, magnetization an chemical composeetion. A semple description is that a phase is a region o material that is chemically uniform, pheesically distinct, an (eften) mechanically separable. In a seestem consistin o ice an watter in a gless jaur, the ice cubes is ae phase, the watter is a seicont phase, an the humid air ower the watter is a third phase. The gless o the jaur is anither separate phase.
