WebSpecific latent heat is the amount of energy required to change the state of 1 kilogram (kg) of a material without changing its temperature. As there are two boundaries, solid/liquid … WebThe values of latent heat for water are: Specific latent heat of fusion = 330 kJ kg -1. Specific latent heat of vaporisation = 2.26 MJ kg -1. Therefore, evaporating 1 kg of water requires roughly seven times more energy than melting the same amount of ice to form water.

WebSpecific latent heat is the energy that is required to change the phase of a 1 kilogram substance at a steady temperature (thus without causing any change in the temperature). Mathematically, the specific latent heat formula is: L=Q ⁄ M. Where, L = Specific Latent Heat, Q = Heat, M = Mass. The unit of specific latent heat is kJ/kg or J/g. WebMar 1, 2024 · Concept: Heat capacity: It is the ratio of the amount of heat supplied to a change in temperature while specific heat capacity is the amount of heat supplied per unit mass per unit change in temperature.; Formula, Heat capacity, \(C=\frac{Q}{Δ T}\), where Q = heat, ΔT = temperature difference Heat capacity can be measured in JK-1.; Calculation: … stehn funeral home milwaukie or https://rubenesquevogue.com
