WitrynaThe 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 … Witryna8 years ago. In this paragraph of heat of vaporization I got a bit confused by these numbers: "Water’s heat of vaporization depends on the temperature: it's around 540 cal/g at 100 °C (water's boiling point) and around 580 cal/g at 25 °C (room temperature)." WitrynaLower heating (calorific) value (LHV): The higher heating value less the latent heat of vaporization of the water vapour formed by the combustion of the hydrogen in the fuel. 低发（产）热值：高发热值减去燃料中氢燃烧形成的水蒸汽蒸发产生的潜在热量。 starlight halo 2023 royal high
