Exempel på hur man kan använda SUBSTANCES i en mening

• Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells.
• BSI is similar in nature to universal precautions, but goes further in isolating workers from pathogens, including substances now known to carry HIV.
• It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
• Some definitions specify that the particles must be dispersed in a liquid, while others extend the definition to include substances like aerosols and gels.
• Combustion does not always result in fire, because a flame is only visible when substances undergoing combustion vaporize, but when it does, a flame is a characteristic indicator of the reaction.
• A chemical element is a chemical substance that cannot be broken down into other substances by chemical reactions.
• A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another.
• The classical elements typically refer to earth, water, air, fire, and (later) aether which were proposed to explain the nature and complexity of all matter in terms of simpler substances.
• Carcinogens can include synthetic chemicals, naturally occurring substances, physical agents such as ionizing and non-ionizing radiation, and biologic agents such as viruses and bacteria.
• drug policy under which the manufacture, importation, possession, use, and distribution of certain substances is regulated.
• Distillation, also classical distillation, is the process of separating the component substances of a liquid mixture of two or more chemically discrete substances; the separation process is realized by way of the selective boiling of the mixture and the condensation of the vapors in a still.
• Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that do not require consideration of quantum effects.
• Equations of state are useful in describing the properties of pure substances and mixtures in liquids, gases, and solid states as well as the state of matter in the interior of stars.
• An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances.
• His synthesis of the organic compound urea in the laboratory from inorganic substances contradicted the belief that organic compounds could only be produced by living organisms due to a "life force".
• They have zero shear modulus, or, in simpler terms, are substances which cannot resist any shear force applied to them.
• Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different.
• When exposed to ultraviolet radiation, many substances will glow (fluoresce) with colored visible light.
• Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from substances that are already present in the battery.
• Food additives are substances added to food to preserve flavor or enhance taste, appearance, or other sensory qualities.
