  2. Thermal equilibrium - Wikipedia

    en.wikipedia.org/wiki/Thermal_equilibrium

    When it is completely settled, so that macroscopic change is no longer detectable, it is in its own thermal equilibrium. It is not implied that it is necessarily in other kinds of internal equilibrium. For example, it is possible that a body might reach internal thermal equilibrium but not be in internal chemical equilibrium; glass is an ...

  3. Laws of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Laws_of_thermodynamics

    A prime example of this irreversibility is the transfer of heat by conduction or radiation. It was known long before the discovery of the notion of entropy that when two bodies, initially of different temperatures, come into direct thermal connection, then heat immediately and spontaneously flows from the hotter body to the colder one.

  4. Equilibrium thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Equilibrium_thermodynamics

    An equilibrium state is mathematically ascertained by seeking the extrema of a thermodynamic potential function, whose nature depends on the constraints imposed on the system. For example, a chemical reaction at constant temperature and pressure will reach equilibrium at a minimum of its components' Gibbs free energy and a maximum of their entropy.

  5. Thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Thermodynamics

    This statement implies that thermal equilibrium is an equivalence relation on the set of thermodynamic systems under consideration. Systems are said to be in equilibrium if the small, random exchanges between them (e.g. Brownian motion) do not lead to a net change in energy. This law is tacitly assumed in every measurement of temperature.

  6. Zeroth law of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Zeroth_law_of_thermodynamics

    If it is defined that a thermodynamic system is in thermal equilibrium with itself (i.e., thermal equilibrium is reflexive), then the zeroth law may be stated as follows: If a body C, be in thermal equilibrium with two other bodies, A and B, then A and B are in thermal equilibrium with one another. [8]

  7. Thermodynamic state - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_state

    A few different types of equilibrium are listed below. Thermal equilibrium: When the temperature throughout a system is uniform, the system is in thermal equilibrium. Mechanical equilibrium: If at every point within a given system there is no change in pressure with time, and there is no movement of material, the system is in mechanical ...

    For example, higher tariffs could help boost American manufacturing jobs if more businesses decide they want their goods made domestically to avoid the added cost of importing.

  9. Thermodynamic equilibrium - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_equilibrium

    Thermodynamic equilibrium is a notion of thermodynamics with axiomatic status referring to an internal state of a single thermodynamic system, or a relation between several thermodynamic systems connected by more or less permeable or impermeable walls.
