  2. Acetylacetone - Wikipedia

    en.wikipedia.org/wiki/Acetylacetone

    Pentane-2,4-dione (keto form) Other names ... temperature. 340 °C (644 °F; 613 K) ... In some cases the chelate effect is so strong that no added base is needed to ...

  3. Temperature dependence of viscosity - Wikipedia

    en.wikipedia.org/wiki/Temperature_dependence_of...

    While correctly predicting the increase of gaseous viscosity with temperature, the / trend is not accurate; the viscosity of real gases increases more rapidly than this. Capturing the actual T {\displaystyle T} dependence requires more realistic models of molecular interactions, in particular the inclusion of attractive interactions which are ...

  4. Pentanedione - Wikipedia

    en.wikipedia.org/wiki/Pentanedione

    Pentanedione may refer to: Acetylacetone (2,4-pentanedione) Acetylpropionyl (2,3-pentanedione) See also. C 5 H 8 O 2; Cyclopentanedione

  5. Enthalpy of vaporization - Wikipedia

    en.wikipedia.org/wiki/Enthalpy_of_vaporization

    Temperature-dependency of the heats of vaporization for water, methanol, benzene, and acetone. In thermodynamics, the enthalpy of vaporization (symbol ∆H vap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas.

  6. Metal acetylacetonates - Wikipedia

    en.wikipedia.org/wiki/Metal_acetylacetonates

    The anhydrous form exists as the tetramer [Co(acac) 2] 4. Like the trimeric nickel complex, this tetramer shows ferromagnetic interactions at low temperatures. [21] Ir(acac) 3 and Rh(acac) 3 are known. A second linkage isomer of the iridium complex is known, trans-Ir(acac) 2 (CH(COMe) 2)(H 2 O).

  7. Radiative forcing - Wikipedia

    en.wikipedia.org/wiki/Radiative_forcing

    An estimated value of ~ gives an increase in global temperature of about 1.6 K above the 1750 reference temperature due to the increase in CO 2 over that time (278 to 405 ppm, for a forcing of 2.0 W/m 2), and predicts a further warming of 1.4 K above present temperatures if the CO 2 mixing ratio in the atmosphere were to become double its pre ...

  8. Volume correction factor - Wikipedia

    en.wikipedia.org/wiki/Volume_Correction_Factor

    In thermodynamics, the Volume Correction Factor (VCF), also known as Correction for the effect of Temperature on Liquid (CTL), is a standardized computed factor used to correct for the thermal expansion of fluids, primarily, liquid hydrocarbons at various temperatures and densities. [1]

  9. Plasma parameters - Wikipedia

    en.wikipedia.org/wiki/Plasma_parameters

    The SI unit of temperature is the kelvin (K), but using the above relation the electron temperature is often expressed in terms of the energy unit electronvolt (eV). Each kelvin (1 K) corresponds to 8.617 333 262 ... × 10 −5 eV ; this factor is the ratio of the Boltzmann constant to the elementary charge . [ 6 ]
