SpletFor comparison to the thought experiment in the question above, note that the heat is proportional to the water in the salt+water mix. For example, with 100g/mg salt, i.e. 900g/kg water, the latent heat at 100C is 0.9*2256.5 = 2030.8.

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.

7.2: Specific Heat and Latent Heat Capacity of Water

SpletWater’s heat of vaporization is around 540 cal/g at 100 °C, water's boiling point. Note that some molecules of water – ones that happen to have high kinetic energy – will escape from the surface of the water even at lower temperatures. As water molecules evaporate, … Splet29. mar. 2024 · The latent heat of the fusion of 5 kg of water is 1670 kJ. To find this number on your own, you need to multiply the specific latent heat of the fusion of water ( 334 kJ/kg) times the mass of the water ( 5 kg ). … blay interview

11.3 Phase Change and Latent Heat - Physics OpenStax

SpletLatent heat of fusion is the heat required to melt ice (80 cal/g), and latent heat of vaporization is the heat required to turn liquid water into water vapor (540 cal/g) (PW). The high heat capacity of water helps regulate global climate, as the oceans slowly absorb and release heat, preventing rapid swings in temperature (see section 8.1). It ... SpletAnswer: The amount of heat required to heat 1 gram of pure liquid water from 10°C to 20°C can be calculated using the specific heat formula: Explanation: Q = m * c * ΔT. where Q is … blay jean yves
