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.
A phase diagram is a graphical representation that shows the phase of a substance at various temperatures, pressures, compositions and volumes. |
INTRODUCTION. • A Phase is an homogeneous portion of a material system that has uniform phy- sical and chemical characteristics. |
Phase, in thermodynamics, chemically and physically uniform or homogeneous quantity of matter that can be separated mechanically from a nonhomogeneous mixture. |
