  2. List of states of matter - Wikipedia

    en.wikipedia.org/wiki/List_of_states_of_matter

    Such states of matter are studied in condensed matter physics. In extreme conditions found in some stars and in the early universe, atoms break into their constituents and matter exists as some form of degenerate matter or quark matter. Such states of matter are studied in high-energy physics.

  3. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    The term phase is sometimes used as a synonym for state of matter, but it is possible for a single compound to form different phases that are in the same state of matter. For example, ice is the solid state of water, but there are multiple phases of ice with different crystal structures , which are formed at different pressures and temperatures.

  4. Matter - Wikipedia

    en.wikipedia.org/wiki/Matter

    [1]: 21 [2] Matter exists in various states (also known as phases). These include classical everyday phases such as solid, liquid, and gas – for example water exists as ice, liquid water, and gaseous steam – but other states are possible, including plasma, Bose–Einstein condensates, fermionic condensates, and quark–gluon plasma. [3]

  5. Physical object - Wikipedia

    en.wikipedia.org/wiki/Physical_object

    A physical body is an enduring object that exists throughout a particular trajectory of space and orientation over a particular duration of time, and which is located in the world of physical space (i.e., as studied by physics). This contrasts with abstract objects such as mathematical objects which do not exist at any particular time or place.

  6. Plasma (physics) - Wikipedia

    en.wikipedia.org/wiki/Plasma_(physics)

    Plasma is called the fourth state of matter after solid, liquid, and gas. [16] [17] [18] It is a state of matter in which an ionized substance becomes highly electrically conductive to the point that long-range electric and magnetic fields dominate its behaviour. [19] [20]

  7. Universe - Wikipedia

    en.wikipedia.org/wiki/Universe

    The great majority of ordinary matter in the universe is unseen, since visible stars and gas inside galaxies and clusters account for less than 10 percent of the ordinary matter contribution to the mass–energy density of the universe. [125] [126] [127] Ordinary matter commonly exists in four states (or phases): solid, liquid, gas, and plasma ...

  8. Quark - Wikipedia

    en.wikipedia.org/wiki/Quark

    SU(3) c color transformations correspond to "rotations" in color space (which, mathematically speaking, is a complex space). Every quark flavor f , each with subtypes f B , f G , f R corresponding to the quark colors, [ 79 ] forms a triplet: a three-component quantum field that transforms under the fundamental representation of SU(3) c . [ 80 ]

  9. Astrophysical plasma - Wikipedia

    en.wikipedia.org/wiki/Astrophysical_plasma

    The accepted view of scientists is that much of the baryonic matter in the universe exists in this state. [3] When matter becomes sufficiently hot and energetic, it becomes ionized and forms a plasma. This process breaks matter into its constituent particles which includes negatively charged electrons and positively charged ions. [4]
