For instance, water is a chemical made when two hydrogen atoms bond to 1 oxygen atom. Its chemical components is H2O. Chemical additionally might be an adjective to explain properties of supplies which can be the results of numerous reactions between totally different compounds.
chemical response: A course of that includes 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 circulation.
copper: A metallic chemical aspect 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 units.
present: A fluid — equivalent to of water or air — that strikes in a recognizable course. (in electrical energy) The circulation of electrical energy or the quantity of cost shifting by way of some materials over a specific time frame.
knowledge: Details and/or statistics collected collectively for evaluation however not essentially organized in a manner that offers them that means. For digital info (the sort saved by computer systems), these knowledge usually are numbers saved in a binary code, portrayed as strings of zeros and ones.
detergent: A compound derived from petroleum merchandise, typically used for cleansing. Detergents work by breaking apart and surrounding dust particles or oily substances, in order that they are often washed away with water.
digital: (in pc science and engineering) An adjective indicating that one thing has been developed numerically on a pc or on another digital gadget, based mostly on a binary system (the place all numbers are displayed utilizing a sequence of solely zeros and ones).
electrical cost: The bodily property chargeable for electrical drive; it may be adverse or constructive.
electrical present: A circulation of electrical cost — electrical energy — often from the motion of negatively charged particles, referred to as electrons.
electrical energy: A circulation of cost, often from the motion of negatively charged particles, referred to as electrons.
electrochemical: An adjective for processes by which electrical energy impacts chemical adjustments in some substance and in addition how chemical vitality might 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 (equivalent to a transistor) that both releases or collects electrons (adverse expenses) or holes (constructive expenses) — or that may management their motion.
electrolyte: A non-metallic liquid or strong that conducts ions — electrically charged atoms or molecules — to hold electrical expenses. (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 expenses 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 subject. This time period can be utilized to the bodily drive (the electromagnetic drive) that governs interactions between charged particles and that are as a consequence of 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 constituted 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 because of the loss or achieve of a number of electrons. An ionized gasoline, or plasma, is the place all the electrons have been separated from their guardian atoms.
LED: (brief for mild emitting diode) Digital parts that, as their identify suggests, emit mild when electrical energy flows by way of them. LEDs are very energy-efficient and sometimes might be very vibrant. They’ve these days been changing typical lights for dwelling and industrial lamps.
liquid: A fabric that flows freely however retains a continuing quantity, like water or oil.
magnetism: The engaging affect, or drive, created by sure supplies, referred to as magnets, or by the motion of electrical expenses.
metallic: One thing that conducts electrical energy effectively, tends to be shiny (reflective) and is malleable (that means it may be reshaped with warmth and never an excessive amount of drive or strain).
nickel: Quantity 28 on the periodic desk of components, this tough, silvery aspect resists oxidation and corrosion. That makes it a very good coating for a lot of different components or to be used in multi-metal alloys.
particle: A minute quantity of one thing.
plastic: Any of a sequence of supplies which can be simply deformable; or artificial supplies which were constituted of polymers (lengthy strings of some building-block molecule) that are typically light-weight, cheap and proof against degradation.
preliminary: An early step or stage that precedes one thing extra essential.
salt: A compound made by combining an acid with a base (in a response that additionally creates water). The ocean accommodates many various salts — collectively referred to as “sea salt.” Frequent desk salt is a fabricated from sodium and chlorine.
answer: A liquid through which one chemical has been dissolved into one other.
sq.: (in geometry) A rectangle with 4 sides of equal size.
Styrofoam: A trademarked identify for a sort of inflexible foam constituted of lightweight polystyrene plastic. It’s used for every part from dwelling craft initiatives to ornamental ornaments and constructing insulation.
voltage: A drive related to an electrical present that’s measured in models generally known as volts. Energy firms use high-voltage to maneuver electrical energy over lengthy distances.
