Web29 mrt. 2024 · Latent heat is the total energy released or absorbed during a phase transition of a substance. You find it by multiplying the specific latent heat of a substance by its mass. It's also known as the heat of transformation. Specific heat capacity is the energy released or absorbed with the change in temperature by exactly 1 kelvin per 1 kilogram of substance.

Web5 apr. 2016 · Latent heat of vapourisation of water at 1 bar, 100 ∘ C is 2257 k J k g. Which means, that much heat is required to break inter-molecular forces and turn into gasoeus phase. As pressure on molecules increases they require more heat to overcome the pressure force acting or to escape and thus latent heat required is more.

WebWater’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, the surface they evaporate from gets cooler, a process called evaporative cooling.
