For melting or freezing (phase … WebThe latent heat associated with melting a solid or freezing a liquid is called the heat of fusion; that associated with vaporizing a liquid or a solid or condensing a vapour is called the heat of vaporization.
WebApr 9, 2024 · The formula for latent heat is given by, L = Q / M L = 300 / 5 L = 60 k.cal/kg Hence latent heat value is 60 k.cal/kg 2. At 20°C, a piece of metal has a density of 60g. When immersed in a steam current at 100°C, 0.5g of the steam condenses on it. Provided that the latent heat of steam is 540 cal/g, calculate the specific heat of the metal. 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: $${\displaystyle L_{\text{water}}(T)\approx \left(2500.8-2.36T+0.0016T^{2}-0.00006T^{3}\right)~{\text{J/g}},}$$ where the temperature … 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 As the temperature (or pressure) rises to the critical point, the latent heat of vaporization falls to zero. 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; they depend on the properties of the body. ″Sensible heat″ is ″sensed″ or felt in a … 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 See more • Bowen ratio • Eddy covariance flux (eddy correlation, eddy flux) • Sublimation (physics) See more
