WebThe latent heat of fusion is the enthalpy change of any amount of substance when it melts. When the heat of fusion is referenced to a unit of mass, it is usually called the specific heat of fusion, while the molar heat of fusionrefers to the enthalpy change per amount of substancein moles. WebThe heat required to melt a solid can be calculated as. q = L m m (1) where . q = required heat (J, Btu) L m = latent heat of melting (J/kg, Btu/lb) m = mass of substance (kg, lb) Example - Required Heat to melt Ice to Water. The heat required to melt 10 kg of ice to water can be calculated as. q = L m m
WebViews: 5,652. In an X-ray tube, electrons are accelerated through a potential difference of 75kV. The electrons then strike a tungsten target of effective mass 15g. The electron energy is converted into the energy of X-ray photons with an efficiency of 5.0%. The rest of the energy is converted into thermal energy. WebWhen water boils: energy is required to completely separate the molecules until there are no longer forces of attraction between the molecules, hence this requires much more energy; Worked example: Specific latent heat. The energy needed to boil a mass of $530 \mathrm{~g}$ of a liquid is $0.6 \mathrm{MJ}$.
