The state of being liquid through heat; fusion.

Any substance or mixture used to promote the fusion of metals or minerals, as alkalies, borax, lime, fluorite.

To cause to become fluid; to fuse.

An aggressive chemical, usually contained in the solder wire, which will clean the areas about to be jointed.

The act of flowing; a continuous moving on or passing by, as of a flowing stream; constant succession; change.

The quantity of a fluid that crosses a unit area of a given surface in a unit of time.

Flowing; unstable; inconstant; variable.

the rate at which heat (energy, radiation, carbon dioxide, water vapour etc) flows across unit area (e.g. heat flux is the flow of heat in a heat exchange process)

The strength of a magnetic field represented by lines of force. Symbol f

A measure of the density of magnetic field lines over a surface area. Flux/area is proportional to the average force on a charged particle on the surface.

See Magnetic Field

invisible lines of force that extend around a magnetic material. The greatest density is at the two poles of the magnet.

A fluid discharge from the bowels or other part; especially, an excessive and morbid discharge; as, the bloody flux or dysentery. See Bloody flux.

The matter thus discharged.

To cause a discharge from; to purge.

A Watery discharge or diarrhoea

luminous intensity, usually of a light source, per unit solid angle; unit: lumen

Unit is erg/sec or watts.

The basic unit of optical power. Radiometric flux is expressed in watts. All wavelengths of the electromagnetic spectrum are included.

Flux is a measure of light power. Radiometric flux, expressed in watts, includes light at all wavelengths of the spectrum; ultraviolet (200 to 400 nm), visible (400 to 700 nm), and infrared (700 to 30000 nm). Luminous flux is a measure of photometric power. Photometric flux, expressed in lumens, includes only visible light, and is weighted to match the responsivity of the human eye, which is most sensitive to yellow-green.

Rate of transfer of a quantity (water, heat, etc.) across a surface.

become liquid or fluid when heated; "the frozen fat liquefied"

The rate that energy crosses a given surface (real or imaginary).

The rate of transfer of fluid, particles, or energy across a given surface.

movement of water or material from one place to another.

(1) A bituminous material used as a feed stock for further processing and as a material to soften other bituminous materials; (2) To remeltthe coating asphalt on the back of an asphalt or modified bitumen cap sheet during application.

A liquid, normally diesel or oil, added to bitumen to give a long term reduction in viscosity.
