• ### Heat of Fusion of Ice – Discussion of Theory

Heat lost by water is equal to the mass times the specific latent heat of fusion and the equation is VtI=ML, M is mass of water in difference, t stands for the time taken for heat the ice and L is the latent heat of fusion of ice. ThereforeL ==∵=2700J ∴L=2.7×105Jkg-1 and it is not very similar to the exact value of the latent heat of fusion of ice, which is 3.3×105 Jkg-1. Next part is ...

For example, when a pot of water is kept boiling, the temperature remains at 100 °C (212 °F) until the last drop evaporates, because all the heat being added to the liquid is absorbed as latent heat of vaporization and carried away by the escaping vapour molecules.Similarly, while ice melts, it remains at 0 °C (32 °F), and the liquid water that is formed with the latent heat of fusion is ...

• ### Latent heat - Wikipedia

Latent heat (also known as latent energy, or as Heat of Transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition.. Latent heat can be understood as energy in hidden form which is supplied or extracted to change the state of a substance without changing its temperature.

Similarly, while ice melts, it remains at 0 °C (32 °F), and the liquid water that is formed with the latent heat of fusion is also at 0 °C. The heat of fusion for water at 0 °C is approximately 334 joules (79.7 calories) per gram, and the heat of vaporization at 100 °C is about 2,230 joules (533 calories) per gram.

Based on our experiment the latent heat of vaporization of water is 2478630 L/kg, which is close to the table value; 2300000 J/kg. By this we can calculate that our result is 7. 3% higher than the expected table value number. Evaluation: There’s a linear line seen on the graph, where you can determine the L of water.

The (latent) heat of vaporization (∆H vap) also known as the enthalpy of vaporization or evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance, to transform a given quantity of the substance into a gas.. The enthalpy of vaporization is a function of the pressure at which that transformation takes place. The heat of vaporization diminishes with increasing ...
