Physicists recognize three types of latent heat, corresponding to the changes of phase between solid, liquid, and gas: The latent heat of fusion, L f. This is the heat per kilogram needed to make the change between the solid and liquid phases, as when water turns to ice or ice turns to water.
Laten Heat of Fusion Physic 20 IB Lab Latent Heat (kJ/Kg) 22.00 319 30.00 319 38.00 319 Conclusion: In the preceding lab, it is noticeable that water temperature does not affect the latent heat of fusion. Therefore the lab is a success and has proven that latent heat is indeed a constant.
Latent heat of fusion is the heat required to change the solid from solid to liquid state without any change in temperature.Latent heat of fusion of ice is 336000 J/kg.While Latent heat of vaporization is the heat required to change the liquid from liquid to vapour state without any change in temperature. Latent Heat of …

Latent heat of fusion

latent heat definition: 1. the heat that is absorbed or released by a substance when it changes state, for example from a…. Learn more. Cambridge Dictionary +Plus The purpose of this lab was to find the heat of fusion of ice using a simple calorimeter. Procedure: Approximately 125-mL of tap water were heated in a 250-mL beaker with a Bunsen burner to a temperature of 50°C . The water was then removed from the heat and 100-mL of the warm water were measured out using a graduated cylinder. Defining specific heat, heat of fusion, and heat of vaporization. How to calculate the amount of heat to change the temperature of water and the energy required to change for a phase change. If you're seeing this message, it means we're having trouble loading external resources on our website. Latent heat of fusion is calculated as. L = 1000 L mol / A (1) where . L = latent heat of fusion (kJ/kg) L mol = latent heat of fusion (kJ/mol) A = atomic weight (g/mol) Note that atomic mass and atomic weight are two different things. Atomic mass is the mass of an individual element. Atomic weight is the average mass of all the isotopes of an ... Latent heat of fusion is the change in enthalpy of any amount of substance when it changes from solid state to liquid state. The temperature at which this occurs is known as the melting point of that substance. When a substance melts, it absorbs energy. The temperature remains constant when the substance melts.
