  2. Joule–Thomson effect - Wikipedia

    en.wikipedia.org/wiki/Joule–Thomson_effect

    The rate of change of temperature with respect to pressure in a Joule–Thomson process (that is, at constant enthalpy ) is the Joule–Thomson (Kelvin) coefficient. This coefficient can be expressed in terms of the gas's specific volume V {\displaystyle V} , its heat capacity at constant pressure C p {\displaystyle C_{\mathrm {p} }} , and its ...

  3. Dulong–Petit law - Wikipedia

    en.wikipedia.org/wiki/Dulong–Petit_law

    An equivalent statement of the Dulong–Petit law in modern terms is that, regardless of the nature of the substance, the specific heat capacity c of a solid element (measured in joule per kelvin per kilogram) is equal to 3R/M, where R is the gas constant (measured in joule per kelvin per mole) and M is the molar mass (measured in kilogram per mole).

  4. Mechanical equivalent of heat - Wikipedia

    en.wikipedia.org/wiki/Mechanical_equivalent_of_heat

    In particular Joule had experimented on the amount of mechanical work generated by friction needed to raise the temperature of a pound of water by one degree Fahrenheit and found a consistent value of 778.24 foot pound force (4.1550 J·cal −1). Joule contended that motion and heat were mutually interchangeable and that, in every case, a given ...

  5. Joule effect - Wikipedia

    en.wikipedia.org/wiki/Joule_effect

    Between 1840 and 1843, Joule carefully studied the heat produced by an electric current. From this study, he developed Joule's laws of heating, the first of which is commonly referred to as the Joule effect. Joule's first law expresses the relationship between heat generated in a conductor and current flow, resistance, and time. [1]

  6. Molar heat capacity - Wikipedia

    en.wikipedia.org/wiki/Molar_heat_capacity

    The value obtained this way is said to be the molar heat capacity at constant volume (or isochoric) and denoted c V,m, c v,m, c v,m, etc. The value of c V,m is always less than the value of c P,m. This difference is particularly notable in gases where values under constant pressure are typically 30% to 66.7% greater than those at constant ...

  7. Dimensionless physical constant - Wikipedia

    en.wikipedia.org/.../Dimensionless_physical_constant

    The fine-structure constant is fixed to the strength of the electromagnetic force. At low energies, α ≈ ⁠ 1 / 137 ⁠, whereas at the scale of the Z boson, about 90 GeV, one measures α ≈ ⁠ 1 / 127 ⁠. There is no accepted theory explaining the value of α; Richard Feynman elaborates:
