  2. List of states of matter - Wikipedia

    en.wikipedia.org/wiki/List_of_states_of_matter

    Strange matter: A type of quark matter that may exist inside some neutron stars close to the Tolman–Oppenheimer–Volkoff limit (approximately 2–3 solar masses). May be stable at lower energy states once formed. Quark matter: Hypothetical phases of matter whose degrees of freedom include quarks and gluons Color-glass condensate

  3. Biogeochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Biogeochemical_cycle

    A biogeochemical cycle, or more generally a cycle of matter, [1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle , the nitrogen cycle and the water cycle .

  4. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    In regular cold matter, quarks, fundamental particles of nuclear matter, are confined by the strong force into hadrons that consist of 2–4 quarks, such as protons and neutrons. Quark matter or quantum chromodynamical (QCD) matter is a group of phases where the strong force is overcome and quarks are deconfined and free to move.

  5. Laws of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Laws_of_thermodynamics

    When matter is transferred into a system, the internal energy and potential energy associated with it are transferred into the new combined system. ( u Δ M ) i n = Δ U s y s t e m {\displaystyle \left(u\,\Delta M\right)_{\rm {in}}=\Delta U_{\rm {system}}} where u denotes the internal energy per unit mass of the transferred matter, as measured ...

  6. Hindu cosmology - Wikipedia

    en.wikipedia.org/wiki/Hindu_cosmology

    Hindu cosmology is the description of the universe and its states of matter, cycles within time, physical structure, and effects on living entities according to Hindu texts. Hindu cosmology is also intertwined with the idea of a creator who allows the world to exist and take shape. [1]

  7. Science education - Wikipedia

    en.wikipedia.org/wiki/Science_education

    Physics education is characterized by the study of science that deals with matter and energy, and their interactions. [11] Physics First, a program endorsed by the American Association of Physics Teachers, is a curriculum in which 9th grade students take an introductory physics course. The purpose is to enrich students' understanding of physics ...

  8. Rock cycle - Wikipedia

    en.wikipedia.org/wiki/Rock_cycle

    This diamond is a mineral from within an igneous or metamorphic rock that formed at high temperature and pressure. The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous.

  9. Phase (matter) - Wikipedia

    en.wikipedia.org/wiki/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.
