WebSolution: The energy for a state change equals the mass multiplied by the specific latent heat. In this case, m = 0.5 kg. L = 334000 J/kg. Energy required, E = m × L = 0.5 kg × 334000 J/kg = 167,000 J. Problem 2: Calculate the energy required to convert 0.15kg of ethanol from a liquid to a vapor.

WebOverview. The 'enthalpy' of fusion is a latent heat, because, while melting, the heat energy needed to change the substance from solid to liquid at atmospheric pressure is latent … 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. stryx lip balm

WebJan 24, 2024 · Ans: It is the pressure at which the liquid will change to vapour without boiling. At critical pressure and critical temperature, the latent heat of vapourization of … WebSpecific latent heat. 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 1 kg, of a substance as an intensive … WebOn the other hand, the latent heat was dominant after 13.00 o’clock. Due to the fins, the seawater in Cases B and C was at a higher temperature than that in Case A, and then a high rate of evaporation occurred in Cases B and C. Increasing the fin number raised the latent heat; consequently, the useful heat for Case C was higher. stryx 1978
