1.6: Phase Changes

Phase transitions play an important theoretical and practical role in the study of heat flow. In melting (or "fusion"), a solid turns into a liquid; the opposite process is freezing evaporation, a liquid turns into a gas; the opposite process is condensation. A substance melts or freezes at a temperature called its melting point, and boils (evaporates rapidly) or condenses at its ...

Can I Get 3-Phase Power At Home

A single phase consists of a two-wire AC power circuit, a neutral wire and a power wire. Compare this to 3 phase which is a four-wire circuit with a neutral wire and three power wires. Therefore it can be quite a long job depending on other factors. The new 3 phase panel will have to be installed and the current distribution one removed.

3.2: Energy of Phase Changes

Energy Changes That Accompany Phase Changes. Phase changes are always accompanied by a change in the energy of a system. For example, converting a liquid, in which the molecules are close together, to a gas, in which the molecules are, on average, far apart, requires an input of energy (heat) to give the molecules enough kinetic energy to allow them to …

14.7: Phase Change and Latent Heat

Even more energy is required to vaporize water; it would take 2256 kJ to change 1 kg of liquid water at the normal boiling point ((100^{circ} mathrm{C}) at atmospheric pressure) to steam (water vapor). This example shows that the energy for a phase change is enormous compared to energy associated with temperature changes without a phase change.
