  2. List of states of matter - Wikipedia

    en.wikipedia.org/wiki/List_of_states_of_matter

    Ferromagnetism: A state of matter with spontaneous magnetization. Antiferromagnetism: A state of matter in which the neighboring spin are antiparallel with each other, and there is no net magnetization. Ferrimagnetism: A state in which local moments partially cancel. Altermagnetism: A state with zero net magnetization and spin-split electronic ...

  3. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    Forms of matter that are not composed of molecules and are organized by different forces can also be considered different states of matter. Superfluids (like Fermionic condensate) and the quark–gluon plasma are examples. In a chemical equation, the state of matter of the chemicals may be shown as (s) for solid, (l) for liquid, and (g) for gas.

  4. Laws of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Laws_of_thermodynamics

    The zeroth law of thermodynamics defines thermal equilibrium and forms a basis for the definition of temperature: If two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. The first law of thermodynamics states that, when energy passes into or out of a system (as work, heat, or ...

  5. Thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Thermodynamics

    The third law of thermodynamics states: As the temperature of a system approaches absolute zero, all processes cease and the entropy of the system approaches a minimum value. This law of thermodynamics is a statistical law of nature regarding entropy and the impossibility of reaching absolute zero of temperature. This law provides an absolute ...

  6. Equation of state - Wikipedia

    en.wikipedia.org/wiki/Equation_of_state

    Equations of state are also used for the modeling of the state of matter in the interior of stars, including neutron stars, dense matter (quark–gluon plasmas) and radiation fields. A related concept is the perfect fluid equation of state used in cosmology. Equations of state are applied in many fields such as process engineering and petroleum ...

  7. Phase rule - Wikipedia

    en.wikipedia.org/wiki/Phase_rule

    A phase is a form of matter that is homogeneous in chemical composition and physical state.Typical phases are solid, liquid and gas. Two immiscible liquids (or liquid mixtures with different compositions) separated by a distinct boundary are counted as two different phases, as are two immiscible solids.

  8. Phase (matter) - Wikipedia

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

    Iron-carbon phase diagram, showing the conditions necessary to form different phases. Distinct phases may be described as different states of matter such as gas, liquid, solid, plasma or Bose–Einstein condensate. Useful mesophases between solid and liquid form other states of matter. Distinct phases may also exist within a given state of matter.

  9. Matter - Wikipedia

    en.wikipedia.org/wiki/Matter

    In bulk, matter can exist in several different forms, or states of aggregation, known as phases, [49] depending on ambient pressure, temperature and volume. [50] A phase is a form of matter that has a relatively uniform chemical composition and physical properties (such as density, specific heat, refractive index, and so forth).
