List of states of matter - Wikipedia List of states of matter Matter organizes into various phases or states of matter depending on its constituents and external factors like pressure and temperature Except at extreme temperatures and pressures, atoms form the three classical states of matter: solid, liquid and gas
Matter - Wikipedia Matter is a general term describing any physical substance, which is sometimes defined in incompatible ways in different fields of science Some definitions are based on historical usage from a time when there was no reason to distinguish mass from simply a quantity of matter By contrast, mass is not a substance but a well-defined, extensive property of matter and other substances or systems
State of matter - Wikipedia In physics, a state of matter or phase of matter is one of the distinct forms in which matter can exist Four states of matter are observable in everyday life: solid, liquid, gas, and plasma
List of materials properties - Wikipedia A material property is an intensive property of a material, i e , a physical property or chemical property that does not depend on the amount of the material These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection A property having a fixed value for a given material or substance is
Phase (matter) - Wikipedia Phase (matter) In the physical sciences, a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water
Gas - Wikipedia Macroscopically, the gas characteristics measured are either in terms of the gas particles themselves (velocity, pressure, or temperature) or their surroundings (volume) For example, Robert Boyle studied pneumatic chemistry for a small portion of his career One of his experiments related the macroscopic properties of pressure and volume of a gas
Organic matter - Wikipedia Organic matter, organic material or natural organic matter is the large source of carbon-based compounds found within natural and engineered, terrestrial, and aquatic environments
Elementary particle - Wikipedia The Standard Model of particle physics contains 12 flavors of elementary fermions, plus their corresponding antiparticles, as well as elementary bosons that mediate the forces and the Higgs boson, which was reported on July 4, 2012, as having been likely detected by the two main experiments at the Large Hadron Collider (ATLAS and CMS) [1] The Standard Model is widely considered to be a
