In science, 7th graders usually learn biology, although they may learn physical science or earth science topics too. [citation needed] Foreign language is often introduced in 7th grade, with the most common language taught being Spanish. At many schools 7th graders can choose from several different languages depending on their school's language ...
Strictly speaking, the bulk modulus is a thermodynamic quantity, and in order to specify a bulk modulus it is necessary to specify how the pressure varies during compression: constant- temperature (isothermal ), constant- entropy ( isentropic ), and other variations are possible. Such distinctions are especially relevant for gases .
In colloidal and surface chemistry, the critical micelle concentration ( CMC) is defined as the concentration of surfactants above which micelles form and all additional surfactants added to the system will form micelles. [ 1] The CMC is an important characteristic of a surfactant. Before reaching the CMC, the surface tension changes strongly ...
Order ( Latin: ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class.
