A solenoid voltmeter is a specific type of voltmeter electricians use to test electrical power circuits.

In a solid, constituent particles are closely packed together.

Solid earth refers to "the earth beneath our feet" or terra firma, the planet's solid surface and its interior.

Solid fuel refers to various types of solid material that are used as fuel to produce energy and provide heating, usually released through combustion.

An electrochemical conversion device that produces electricity directly from oxidizing a fuel. Fuel cells are characterized by their electrolyte material such as the solid oxide fuel cell which has a solid oxide or ceramic electrolyte.

The non-volatile matter in a paint composition, i.e. the ingredients. After drying they create the paint film.

Solids control is a process used in drilling rigs which use drilling fluid.

Solid-state electronics means semiconductor electronics: electronic equipment using semiconductor devices such as transistors, diodes and integrated circuits. The term is also used for devices in which semiconductor electronics which have no moving parts replace devices with moving parts, such as the solid-state relay.

A solid state relay is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals.

Solubility is the property of a solid, liquid or gaseous chemical substance called solute to dissolve in a solid, liquid or gaseous solvent.

In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances.

Suggestions to achieve an end goal or alternatives to existing processes.

Solvation (or dissolution) describes the interaction of solvent with dissolved molecules.

A solvent (from the Latin solvō, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution.

It is a 100% solid coating. For practical purposes this may be extended to cover materials containing a small amount of volatile constituent of the binder (solventless).

Liquids, usually volatile, used in the manufacture of paint to dissolve or disperse the binder-forming constituents, and which evaporate during drying and therefore, do not become a part of the dried film.

Sound Navigation Ranging. Electronic equipment which provides the means to search and detect submerged obstructions such as reefs or sunken ships that endanger sea routes.

Equipment used to remove the products of combustion from boiler tubs.

Paints based on unconventional binders, such as epoxies, chlorinated rubbers, vinyls etc.

The acoustic energy emitted by a source as a pressure wave
