Specific latent heat of formation
WebApr 5, 2016 · Latent heat refers to the heat required to overcome molecular bonds. Latent heat of vapourisation of water at 1 bar, 100 ∘ C is 2257 k J k g. Which means, that much heat is required to break inter-molecular forces and turn into gasoeus phase.

Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process. Two common forms of latent heat are latent heat of fusion and latent heat of vaporization . These names describe the direction of energy flow when changing from one phase to the next: from … See more Latent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition See more The English word latent comes from Latin latēns, meaning lying hidden. The term latent heat was introduced into calorimetry around 1750 by Joseph Black—commissioned by producers of Scotch whisky in search of ideal quantities of fuel and water for their … See more The specific latent heat of condensation of water in the temperature range from −25 °C to 40 °C is approximated by the following empirical cubic function: where the temperature $${\displaystyle T}$$ is … See more • Bowen ratio • Eddy covariance flux (eddy correlation, eddy flux) • Sublimation (physics) • Specific heat capacity • Enthalpy of fusion See more The terms ″sensible heat″ and ″latent heat″ refer to energy transferred between a body and its surroundings, defined by the occurrence or non-occurrence of temperature change; … See more A specific latent heat (L) expresses the amount of energy in the form of heat (Q) required to completely effect a phase change of a unit of mass (m), usually 1kg, of a substance as an intensive property: $${\displaystyle L={\frac {Q}{m}}.}$$ Intensive properties … See more As the temperature (or pressure) rises to the critical point, the latent heat of vaporization falls to zero. See more WebThe standard heat of formation of liquid ethanol, ΔH f ° (C 2 H 6 O, l), is -277.6 kJ/mol. The heat of combustion of ethanol, ΔHc° (C2H6O, l) = 2*393.51 + 6*142.915 + (-277.6) = 1366.91 kJ/mol. This can be converted to kJ per mass units: The molweight of ethanol is (2*12.01 + 6*1.01 + 1*16.00) = 46.08 g/mol
