11Mass number — The mass number (A), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. Because protons and neutrons both are baryons, the mass number A is identical… …
12Mass attenuation coefficient — The mass attenuation coefficient is a measurement of how strongly a chemical species or substance absorbs or scatters light at a given wavelength, per unit mass. In addition to visible light, mass attenuation coefficients can be defined for other …
13Mass Party — Not to be confused with the Mass Party of the 1980s and 1990s. The Mass Party was a political party of Thailand s People s Alliance for Democracy. Its main goal was campaigning against Thaksinomics. Origins In May 2006, PAD leaders established… …
14Molecular mass — This article is about the mass of a single molecule. For the mass of a substance commonly used in basic stoichiometric calculations, see Molar mass. Assuming hydrogen and oxygen are standard weights in this image (as opposed to deuterium oxide)… …
15Molar mass — Formula mass redirects here. It is not to be confused with Mass formula. Molar mass, symbol M,[1] is a physical property of a given substance (chemical element or chemical compound), namely its mass per amount of substance.[2] The base SI unit… …
16Thermal mass — Thermal mass, in the most general sense, is any material that has the capacity to store heat. The following discussion pertains to its functional application in ecologically sustainable building construction. When used correctly, it can… …
17Added mass — In fluid mechanics, added mass or virtual mass is the inertia added to a system because an accelerating or decelerating body must move some volume of surrounding fluid as it moves through it, since the object and fluid cannot occupy the same… …
18Conflicts involving Critical Mass — There have been many conflicts during Critical Mass bicycling events resulting in injuries, property damage, and arrests. Both bicyclists and drivers have been victims. Critics say that Critical Mass, a bicycling advocacy event held primarily in… …
19Effective mass — In solid state physics, a particle s effective mass is the mass it seems to carry in the semiclassical model of transport in a crystal. It can be shown that, under most conditions, electrons and holes in a crystal respond to electric and magnetic …
20Semi-empirical mass formula — In nuclear physics, the semi empirical mass formula (SEMF), sometimes also called Weizsäcker s formula, is a formula used to approximate the mass and various other properties of an atomic nucleus. As the name suggests, it is partially based on… …
