  2. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Many intermediate states are known to exist, such as liquid crystal , and some states only exist under extreme conditions, such as Bose–Einstein condensates and Fermionic condensates (in extreme cold), neutron-degenerate matter (in extreme density), and ...

  3. List of states of matter - Wikipedia

    Plasma: Unlike gases, which are composed of neutral atoms, plasma contains a significant number of free electrons and ionized atoms. It may self-generate magnetic fields and electric currents and responds strongly and collectively to electromagnetic forces .

  4. 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]

  5. Microplasma - Wikipedia

    en.wikipedia.org/wiki/Microplasma

    There are 4 states of matter: solid, liquid, gas, and plasma. Plasmas make up more than 99% of the visible universe. Plasmas make up more than 99% of the visible universe. In general, when energy is applied to a gas, internal electrons of gas molecules (atoms) are excited and move up to higher energy levels.

  6. Phase transition - Wikipedia

    en.wikipedia.org/wiki/Phase_transition

    In physics, chemistry, and other related fields like biology, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter: solid, liquid, and gas, and in rare cases, plasma.

  7. Plasma medicine - Wikipedia

    en.wikipedia.org/wiki/Plasma_medicine

    Plasma, often called the fourth state of matter, is an ionized gas containing positive ions and negative ions or electrons, but is approximately charge neutral on the whole. The plasma sources used for plasma medicine are generally low temperature plasmas, and they generate ions, chemically reactive atoms and molecules, and UV-photons.

  9. Bose–Einstein condensate - Wikipedia

    en.wikipedia.org/wiki/Bose–Einstein_condensate

    At one point, when the overlap becomes significant, a macroscopic number of particles condense into the ground state. In condensed matter physics, a Bose–Einstein condensate (BEC) is a state of matter that is typically formed when a gas of bosons at very low densities is cooled to temperatures very close to absolute zero, i.e., 0 K (−273.15 ...
