Its chemical formulation is H₂O. Chemical additionally may be an adjective to explain properties of supplies which can be the results of varied reactions between completely different compounds.

chemical response: A course of that entails the rearrangement of the molecules or construction of a substance, versus a change in bodily type (as from a strong to a gasoline).

conductor: (in physics and engineering) A fabric by way of which {an electrical} present can circulate.

copper: A metallic chemical ingredient in the identical household as silver and gold. As a result of it’s a good conductor of electrical energy, it’s extensively utilized in digital gadgets.

present: A fluid — reminiscent of of water or air — that strikes in a recognizable route. (in electrical energy) The circulate of electrical energy or the quantity of cost transferring by way of some materials over a specific time period.

information: Details and/or statistics collected collectively for evaluation however not essentially organized in a method that provides them that means. For digital info (the kind saved by computer systems), these information sometimes are numbers saved in a binary code, portrayed as strings of zeros and ones.

detergent: A compound derived from petroleum merchandise, usually used for cleansing. Detergents work by breaking apart and surrounding filth particles or oily substances, in order that they are often washed away with water.

digital: (in laptop science and engineering)  An adjective indicating that one thing has been developed numerically on a pc or on another digital gadget, primarily based on a binary system (the place all numbers are displayed utilizing a collection of solely zeros and ones).

electrical cost: The bodily property answerable for electrical power; it may be unfavorable or constructive.

electrical present: A circulate of electrical cost — electrical energy — often from the motion of negatively charged particles, known as electrons.

electrical energy: A circulate of cost, often from the motion of negatively charged particles, known as electrons.

electrochemical: An adjective for processes by which electrical energy impacts chemical modifications in some substance and likewise how chemical vitality may be transformed to electrical vitality or vice versa.

electrode: A tool that conducts electrical energy and is used to make contact with the non-metal a part of {an electrical} circuit, or that contacts one thing by way of which {an electrical} sign strikes. (in electronics) A part of a semiconductor gadget (reminiscent of a transistor) that both releases or collects electrons (unfavorable costs) or holes (constructive costs) — or that may management their motion.

electrolyte: A non-metallic liquid or strong that conducts ions — electrically charged atoms or molecules — to hold electrical costs. (Sure minerals in blood or different bodily fluids can function the ions that transfer to hold a cost.) Electrolytes can also function the ions that transfer constructive costs inside a battery or capacitor.

electromagnetism: The science that has to do with the bodily hyperlinks between electrical energy and magnetism. It’s additionally the time period for the properties of an electrical present that trigger it to generate a magnetic area. This time period can be utilized to the bodily power (the electromagnetic power) that governs interactions between charged particles and that are attributable to their electrical cost and their launch or absorption of sunshine (photons).

electron: A negatively charged particle, often discovered orbiting the outer areas of an atom; additionally, the service of electrical energy inside solids.

glass: A tough, brittle substance made out of silica, a mineral present in sand. Glass often is clear and pretty inert (chemically nonreactive).

ion: (adj. ionized) An atom or molecule with an electrical cost as a result of loss or acquire of a number of electrons. An ionized gasoline, or plasma, is the place the entire electrons have been separated from their father or mother atoms.

LED: (brief for gentle emitting diode) Digital elements that, as their title suggests, emit gentle when electrical energy flows by way of them. LEDs are very energy-efficient and infrequently may be very vivid. They’ve currently been changing standard lights for house and business lamps.

liquid: A fabric that flows freely however retains a relentless quantity, like water or oil.

magnetism: The engaging affect, or power, created by sure supplies, known as magnets, or by the motion of electrical costs.

steel: One thing that conducts electrical energy properly, tends to be shiny (reflective) and is malleable (that means it may be reshaped with warmth and never an excessive amount of power or strain).

nickel: Quantity 28 on the periodic desk of parts, this difficult, silvery ingredient resists oxidation and corrosion. That makes it a very good coating for a lot of different parts or to be used in multi-metal alloys.

particle: A minute quantity of one thing.

plastic: Any of a collection of supplies which can be simply deformable; or artificial supplies which were made out of polymers (lengthy strings of some building-block molecule) that are usually light-weight, cheap and proof against degradation.

preliminary: An early step or stage that precedes one thing extra vital.

salt: A compound made by combining an acid with a base (in a response that additionally creates water). The ocean comprises many alternative salts — collectively known as “sea salt.” Widespread desk salt is a fabricated from sodium and chlorine.

answer: A liquid during which one chemical has been dissolved into one other.

sq.: (in geometry) A rectangle with 4 sides of equal size.

Styrofoam: A trademarked title for a kind of inflexible foam made out of lightweight polystyrene plastic. It’s used for all the things from house craft tasks to ornamental ornaments and constructing insulation.

voltage: A power related to an electrical present that’s measured in models often called volts. Energy firms use high-voltage to maneuver electrical energy over lengthy distances.
