Overall, in scientific contexts the word "medium" refers to a substance or material in which something exists or grows or through which something can move or otherwise travel. The word "medium" and its plural, "media," can have multiple applications in various areas of science, from the soils and other materials for plant growth (growing media) in agriculture to the material that is used to grow bacteria in a biology lab setting (culture media). The word may also appear in certain physics settings, such as an excitable medium or an active laser medium, or in astronomy, such as the interplanetary medium that exists alongside planets in the solar system and the interstellar medium that exists between stars in outer space.Know More
In horticultural contexts, the term "growing medium" can be used to refer to things as simple as soil, or the soil blends that are used as ideal settings for seeds to germinate and plants to flourish. This medium is intended to support and provide nutrients to the plant in addition to facilitating root growth.
In biological contexts, culture media are used in experimental settings in order to grow samples of bacteria, or cultures, for observation and research. Agar is a commonly used culture medium thanks to its solidity and its resistance to degradation.Learn more about Science
Sound is a mechanical wave resulting from the back and forth vibration of the particles of the medium through which the wave is moving. The compressions and rarefactions of sound waves move parallel to the direction of wave propagation, making sound a longitudinal wave.Full Answer >
In chemistry, the term "property" is frequently used to describe the attributes of a substance, such as density, oxidation, state of matter, mass, conductivity, color, bonding and many other traits. These properties are used to understand how a substance behaves in different situations.Full Answer >
A product in science is a substance that is formed when two or more chemicals react. When a chemical reaction takes place, a new substance is often created from the atoms or molecules of the original substances. There are often multiple products formed in a reaction.Full Answer >
In science, particularly in the field of chemistry, solutions are defined as homogeneous mixtures characterized by a uniform consistency throughout the substance. Solutions, which occur at the molecular level, are composed of solutes that are completely dissolved in a solvent. Common solutions include atmospheric air, tap water, beverages, metal alloys, water vapor, salt water, sugar water, orange juice, coffee, dental filling and solder.Full Answer >
