For instance, water is a chemical made when two hydrogen atoms bond to at least one oxygen atom. Its chemical formulation is H2O. Chemical additionally will be an adjective to explain properties of supplies which might be the results of varied reactions between completely different compounds.
chemical engineer: A researcher who makes use of chemistry to unravel issues associated to the manufacturing of meals, gas, medicines and plenty of different merchandise.
chemistry: The sphere of science that offers with the composition, construction and properties of drugs and the way they work together. Scientists use this data to review unfamiliar substances, to breed giant portions of helpful substances or to design and create new and helpful substances. (about compounds) Chemistry is also used as a time period to check with the recipe of a compound, the best way it’s produced or a few of its properties. Individuals who work on this area are referred to as chemists.
present: (in electrical energy) The move of electrical energy or the quantity of cost shifting by some materials over a selected time frame.
electrical present: A move of electrical cost — electrical energy — normally from the motion of negatively charged particles, referred to as electrons.
electrical energy: A move of cost, normally from the motion of negatively charged particles, referred to as electrons.
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 which {an electrical} sign strikes. (in electronics) A part of a semiconductor gadget (comparable to a transistor) that both releases or collects electrons (unfavourable fees) or holes (optimistic fees) — or that may management their motion.
engineer: An individual who makes use of science and math to unravel issues. As a verb, to engineer means to design a tool, materials or course of that can remedy some drawback or unmet want.
equation: In arithmetic, the assertion that two portions are equal. In geometry, equations are sometimes used to find out the form of a curve or floor.
fruit: A seed-containing reproductive organ in a plant.
gel: A gooey or viscous materials that may move like a thick liquid.
graphite: Like diamond, graphite (the substance present in pencil lead) is a type of pure carbon. Not like diamond, graphite may be very mushy. The primary distinction between these two types of carbon is the quantity and sort of chemical bonds between carbon atoms in every substance.

implant: A tool manufactured to exchange a lacking organic construction, to assist a broken organic construction, or to reinforce an current organic construction. Examples embrace synthetic hips, knees and enamel; pacemakers; and the insulin pumps used to deal with diabetes. Or some gadget put in surgically into an animal’s physique to gather data on the person (comparable to its temperature, blood strain or exercise cycle).
mechanical engineer: Somebody skilled in a analysis area that makes use of physics to review movement and the properties of supplies to design, construct and/or take a look at units.
metallic: One thing that conducts electrical energy nicely, 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).
center faculty: A designation for grades six by eight within the U.S. instructional system. It comes instantly previous to highschool. Some faculty methods break their age teams barely completely different, together with sixth grade as a part of elementary faculty after which referring to grades seven and eight as “junior” highschool.
