  3. Specific heat capacity - Wikipedia

    en.wikipedia.org/wiki/Specific_heat_capacity

    The specific heat capacities of iron, granite, and hydrogen gas are about 449 J⋅kg1K1, 790 J⋅kg1K1, and 14300 J⋅kg1K1, respectively. [4] While the substance is undergoing a phase transition , such as melting or boiling, its specific heat capacity is technically undefined, because the heat goes into ...

    en.wikipedia.org/wiki/Ebullioscopic_constant

    In thermodynamics, the ebullioscopic constant K b relates molality b to boiling point elevation. [1] It is the ratio of the latter to the former: = i is the van 't Hoff factor, the number of particles the solute splits into or forms when dissolved. b is the molality of the solution.

    "The kelvin, symbol K, is the SI unit of thermodynamic temperature. It is defined by taking the fixed numerical value of the Boltzmann constant k to be 1.380 649 × 10 −23 when expressed in the unit J K1, which is equal to kg m 2 s −2 K1, where the kilogram, metre and second are defined in terms of h, c and ∆ν Cs."

    Instead the formula that would fit some of the Bonales data is k ≈ 2.0526 - 0.0176TC and not k = -0.0176 + 2.0526T as they say on page S615 and also the values they posted for Alexiades and Solomon do not fit the other formula that they posted on table 1 on page S611 and the formula that would fit over there is k = 2.18 - 0.01365TC and not k ...

  8. Natural units - Wikipedia

    en.wikipedia.org/wiki/Natural_units

    In physics, natural unit systems are measurement systems for which selected physical constants have been set to 1 through nondimensionalization of physical units.For example, the speed of light c may be set to 1, and it may then be omitted, equating mass and energy directly E = m rather than using c as a conversion factor in the typical mass–energy equivalence equation E = mc 2.

    It is defined by taking the fixed numerical value of the Boltzmann constant k to be 1.380 649 × 10 −23 when expressed in the unit J⋅K1, which is equal to kg⋅m 2 ⋅s −2 ⋅K1, where the kilogram, metre and second are defined in terms of h, c and Δν Cs. The kelvin may be expressed directly in terms of the defining constants as:
