  2. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    On the other hand, the maximum water vapor pressure that is thermodynamically stable with the liquid (or solid) at a given temperature is relatively low compared with total atmospheric pressure. For example, if the vapor's partial pressure is 2% of atmospheric pressure and the air is cooled from 25 °C, starting at about 22 °C, water will ...

  3. Human thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Human_thermoregulation

    Simplified control circuit of human thermoregulation. [8] The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus ...

  4. Thermodynamic equilibrium - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_equilibrium

    Classical thermodynamics deals with states of dynamic equilibrium.The state of a system at thermodynamic equilibrium is the one for which some thermodynamic potential is minimized (in the absence of an applied voltage), [2] or for which the entropy (S) is maximized, for specified conditions.

  5. Thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Thermodynamics

    For example, the Helmholtz and Gibbs energies are the energies available in a system to do useful work when the temperature and volume or the pressure and temperature are fixed, respectively. Thermodynamic potentials cannot be measured in laboratories, but can be computed using molecular thermodynamics.

  6. Thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Thermoregulation

    Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.

  7. Thermodynamic temperature - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_temperature

    Thermodynamic temperature is a quantity defined in thermodynamics as distinct from kinetic theory or statistical mechanics.. Historically, thermodynamic temperature was defined by Lord Kelvin in terms of a macroscopic relation between thermodynamic work and heat transfer as defined in thermodynamics, but the kelvin was redefined by international agreement in 2019 in terms of phenomena that are ...

  8. Thermocline - Wikipedia

    en.wikipedia.org/wiki/Thermocline

    Because the warm water is exposed to the sun during the day, a stable system exists and very little mixing of warm water and cold water occurs, particularly in calm weather. Lakes are stratified into three separate layers: the epilimnion (I), metalimnion (II), and (III) hypolimnion .

  9. Thermodynamic state - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_state

    Thermodynamic temperature is a specifically thermodynamic concept, while the original directly measureable state variables are defined by ordinary physical measurements, without reference to thermodynamic concepts; for this reason, it is helpful to regard thermodynamic temperature as a state function.
