The latent heat of evaporation for water is 2256 kJ/kg at atmospheric pressure and 100oC. The heat required to evaporate 10 kg can be calculated as. q = (2256 kJ/kg) (10 kg) = 22560 kJ. Latent heat of vaporization for fluids like alcohol, ether, nitrogen, water and more.
The latent heat calculator helps you compute the energy released or absorbed during a phase transition like melting or vaporizing. In the text below, we explain what is specific latent heat and present a simple latent heat calculation.
17 lip 2023 · To calculate the latent heat of vaporization using this method, follow these steps: Determine the initial and final temperatures of the substance. Measure the corresponding initial and final vapor pressures. Calculate the natural logarithm of the ratio of the vapor pressures.
L is the specific latent heat of vaporization and is the heat required to convert a unit mass of liquid into vapour at the same temperature as the boiling point. L and the boiling temperature, both depend on the pressure. Heat transfer occurs between bodies that are in contact with each other.
Once all the ice has melted, the temperature of the liquid water rises, absorbing heat at a new constant rate. At 100 °C °C, the water begins to boil and the temperature again remains constant while the water absorbs 2256 kJ/kg during this phase change. When all the liquid has become steam, the temperature rises again at a constant rate.
Thermal properties of water at different temperatures like density, freezing temperature, boiling temperature, latent heat of melting, latent heat of evaporation, critical temperature and more. Thermodynamic properties of water: Boiling temperature (at 101.325 kPa): 99.974 °C = 211.953 °F.
