  2. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    State of matter. In physics, a state 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. Many intermediate states are known to exist, such as liquid crystal, and some states only exist under extreme conditions, such as Bose–Einstein ...

  3. List of states of matter - Wikipedia

    en.wikipedia.org/wiki/List_of_states_of_matter

    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. In common temperatures and pressures, atoms form the three classical states of matter: solid, liquid and gas. Complex molecules can also form various mesophases such as liquid ...

  4. Bose–Einstein condensate - Wikipedia

    en.wikipedia.org/wiki/Bose–Einstein_condensate

    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 °C; −459.67 °F). Under such conditions, a large fraction of bosons occupy the lowest quantum state, at which ...

  5. Matter power spectrum - Wikipedia

    en.wikipedia.org/wiki/Matter_power_spectrum

    The matter power spectrum describes the density contrast of the universe (the difference between the local density and the mean density) as a function of scale. It is the Fourier transform of the matter correlation function. On large scales, gravity competes with cosmic expansion, and structures grow according to linear theory.

  6. Equation of state - Wikipedia

    en.wikipedia.org/wiki/Equation_of_state

    In physics and chemistry, an equation of state is a thermodynamic equation relating state variables, which describe the state of matter under a given set of physical conditions, such as pressure, volume, temperature, or internal energy. [1] Most modern equations of state are formulated in the Helmholtz free energy.

  7. Terraria - Wikipedia

    en.wikipedia.org/wiki/Terraria

    Mode (s) Single-player, multiplayer. Terraria ( / təˈrɛəriə / ⓘ tə-RAIR-ee-ə[1]) is a 2011 action-adventure sandbox game developed by Re-Logic. The game was first released for Windows and has since been ported to other PC and console platforms. The game features exploration, crafting, building, painting, and combat with a variety of ...

  8. Phase (matter) - Wikipedia

    en.wikipedia.org/wiki/Phase_(matter)

    v. t. e. 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.

  9. Phase transition - Wikipedia

    en.wikipedia.org/wiki/Phase_transition

    Phase transitions commonly refer to when a substance transforms between one of the four states of matter to another. At the phase transition point for a substance, for instance the boiling point, the two phases involved - liquid and vapor, have identical free energies and therefore are equally likely to exist.
