aerospace: A field of research dedicated to the study of Earth’s atmosphere and space, or of aircraft that travel through the atmosphere and space.
array: A broadly organized group of objects. In some cases, it may be equipment systematically arranged to collect information in a coordinated manner. Array may also refer to something laid out or displayed in such a way that a wide range of related things, such as colors, can be displayed at once. This term can also be applied to various options and choices.
bring to a boil: Heating a liquid to a temperature at which it turns into vapor.
chemicals: A substance formed when two or more atoms combine (combine) in a certain proportion and structure. For example, water is a chemical produced when two hydrogen atoms combine with one oxygen atom. Its chemical formula is H2O. Chemistry can also be used as an adjective to describe the properties of materials that result from various reactions between different compounds.
engineer: A person who uses science and mathematics to solve problems. As a verb, “engineering” means to design a device, material, or process that solves some problem or unmet need.
fossil fuel: Fuels such as coal, petroleum (crude oil), and natural gas that have been produced within the Earth over millions of years from the decaying remains of bacteria, plants, and animals.
fuel: A substance that releases energy during a controlled chemical or nuclear reaction. Fossil fuels (coal, natural gas, oil) are common types that release energy through chemical reactions that occur when heated (usually to the point of combustion).
hydrogen:The lightest element in the universe. As a gas, it is colorless, odorless, and highly flammable. It is an essential part of many of the fuels, fats, and chemicals that make up living tissues. It consists of a single proton (acting as the atomic nucleus) orbited by a single electron.
hydrogen peroxide: A molecule consisting of two hydrogen atoms and two oxygen atoms. It is highly reactive and can kill many small microorganisms, including bacteria.
liquid: A substance that maintains a constant volume while flowing freely, such as water or oil.
methane: Hydrocarbon with chemical formula CH4 (Means 4 hydrogen atoms bonded to one carbon atom). It is a natural component of so-called natural gas. It is also released by the decomposition of plant matter in wetlands and belched by cows and other ruminants. From a climate perspective, methane is 80 times more capable of trapping heat in the Earth’s atmosphere than carbon dioxide, making it a very important greenhouse gas.
nitrogen: A colorless, odorless, non-reactive gaseous element that forms approximately 78 percent of Earth’s atmosphere. Its scientific symbol is N. When fossil fuels are burned, nitrogen is released in the form of nitrogen oxides. Comes in two stable formats. Both have 14 protons in the nucleus. But its nucleus has 14 neutrons. the other is 15. Because of their differences, they are known as nitrogen-14 and nitrogen-15 (or nitrogen-15), respectively. 14N and 15N).
oxidizing agent: A substance that produces oxygen and causes the combustion of another substance, such as a fuel.
oxygen: A gas that makes up about 21% of the Earth’s atmosphere. All animals and many microorganisms require oxygen to facilitate growth (and metabolism).
peroxide: A group of chemicals containing a “divalent” pair of oxygen atoms. Each oxygen atom has an unpaired electron orbiting around it that is available to form bonds (attachments) with other atoms. Peroxide is an oxidizing agent, meaning it can react violently at room temperature. Some are also used as bleaching agents.
rocket: Something propelled into the air or into space, sometimes used as a weapon of war. Rockets typically ascend due to the exhaust gases released when some of the fuel is burned. (v.) Something that flies into space at high speed, as if fueled by combustion.
toxic: Can be toxic or can harm or kill cells, tissues, or whole organisms. A measure of the risk posed by such poisons is their toxicity.
