  2. Second law of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Second_law_of_thermodynamics

    The efficiency solely depends on the temperature difference between the hot and cold thermal reservoirs. Carnot's theorem states: All irreversible heat engines between two heat reservoirs are less efficient than a Carnot engine operating between the same reservoirs.

  3. Entropy as an arrow of time - Wikipedia

    en.wikipedia.org/wiki/Entropy_as_an_arrow_of_time

    An important difference between the past and the future is that in any system (such as a gas of particles) its initial conditions are usually such that its different parts are uncorrelated, but as the system evolves and its different parts interact with each other, they become correlated. [4]

    If your body seems to run hot or you're constantly mopping up sweat, here are several health reasons you might be hot and sweaty all the time. Why You’re Always So Hot and Sweaty Skip to main ...

  5. Temperature - Wikipedia

    en.wikipedia.org/wiki/Temperature

    The 273.15 K difference between K and °C is rounded to 273 K to avoid false precision in the Celsius value. E The 273.15 K difference between K and °C is within the precision of these values. F For a true black-body (which the plasma was not). The Z machine's dominant emission originated from 40 MK electrons (soft x-ray emissions) within the ...

  6. Air current - Wikipedia

    en.wikipedia.org/wiki/Air_current

    Thermals are caused by local differences in temperature, pressure, or impurity concentration in the vertical. Temperature differences can cause air currents because warmer air is less dense than cooler air, causing the warmer air to appear "lighter." Thus, if the warm air is under the cool air, air currents will form as they exchange places.

  7. Scientific theory - Wikipedia

    en.wikipedia.org/wiki/Scientific_theory

    Over time, as successive modifications build on top of each other, theories consistently improve and greater predictive accuracy is achieved. Since each new version of a theory (or a completely new theory) must have more predictive and explanatory power than the last, scientific knowledge consistently becomes more accurate over time.

    Fig. 1. HSL (a–d) and HSV (e–h). Above (a, e): cut-away 3D models of each. Below: two-dimensional plots showing two of a model's three parameters at once, holding the other constant: cylindrical shells (b, f) of constant saturation, in this case the outside surface of each cylinder; horizontal cross-sections (c, g) of constant HSL lightness or HSV value, in this case the slices halfway ...
