Phase transition

In physics, chemistry and biology, a phase transition is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic sta

A small piece of rapidly melting solid argon shows two concurrent phase changes: the transitions from solid to liquid and from gas to liquid (shown by the white condensed water vapour).
Plasma (physics)

Plasma is a state of matter that results from one of the other three classical states having undergone an appreciable degree of ionization. It thus consists of a significant portion of charged particl

…of a medium and another. Commonly the term is used to refer to changes among the basic states of matter: solid, liquid, and gas, and in rare cases, plasma. A phase of a thermodynamic system and the states of matter have uniform physical properties. During a phase transition of a given medium, certain…
Lightning as an example of plasma present at Earth's surface: Typically, lightning discharges 30 kiloamperes at up to 100 megavolts, and emits radio waves, light, X- and even gamma rays. Plasma temperatures can approach 30000 K and electron densities may exceed 1024 m−3.
