Q6.what will be the unit of latent heat
WebApr 4, 2024 · Specific Latent Heat. It is expressed as the amount of energy in the form of heat, denoted by Q, which is required to completely affect a phase change of a unit of mass (m), usually 1 kg of a substance as an intensive property. L=Q/m or Q=mL. Here, Q = Amount of energy released or absorbed during the change of phase of the substance (in KJ or BTU) Webspecific latent heat of fusion = 334 × 1,000 = 334,000 J/kg = 167,000 J (167 kJ) Measuring latent heat. Latent heat can be measured from a heating or cooling curveline graph.

WebJun 17, 2024 · Latent heat is an intensive property measured in units of J/kg. Both Lf and Lv depend on the substance, particularly on the strength of its molecular forces as noted earlier. Lf and Lv are collectively called latent heat coefficients. WebMay 22, 2024 · Latent heat, known also as the enthalpy of vaporization (liquid-to-vapor phase change) or enthalpy of fusion (solid-to-liquid phase change), is the amount of heat added to or removed from a substance to produce a change in phase. This energy breaks down the intermolecular attractive forces, and also must provide the energy necessary to …
