Phase (matter) print that page

Argon_ice_1

In the physical sciences , a phase is a region of space (a thermodynamic system ), throughout which all physical properties of a material are essentially uniform. [ 1 ] Examples of physical properties include density , index of refraction , and chemical composition. A simple description

Phase_diagram_for_pure_substance

For much of the history of the natural sciences people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called particulate theory of matter , was first put forward by the Greek philosophers Leucippus (~490 BC) and Democritus

Phase velocity print that page

The phase velocity of a wave is the rate at which the phase of the wave propagates in space. This is the speed at which the phase of any one frequency component of the wave travels. For such a component, any given phase of the wave (for example, the crest) will appear to travel at

Phase transition print that page

Argon_ice_1

A phase transition is the transformation of a thermodynamic system from one phase or state of matter to another. A phase of a thermodynamic system and the states of matter have uniform physical properties. During a phase transition of a given medium certain properties of the medium

State of matter print that page

Stohrem

gas is the state in which matter expands to occupy whatever volume is available. The state or phase of a given set of matter can change depending on pressure and temperature conditions, transitioning to other phases as these conditions change to favor their existence; for example, solid

Thermodynamic temperature print that page

IceBlockNearJoekullsarlon

Temperature arises from the random submicroscopic vibrations of the particle constituents of matter . These motions comprise the kinetic energy in a substance. More specifically, the thermodynamic temperature of any bulk quantity of matter is the measure of the average kinetic energy of a
