The latent heat of fusion of water and ice introduction upon application of sufficient heat, substances change their physical state generally but not always, these changes of state proceed from the solid to the liquid state and then from the liquid to the gaseous state as the substance are heated in this experiment these changes of state will be. Finding the latent heat of fusion of ice introduction in this experiment, i will attempt to determine the specific heat capacity of fusion of ice “the specific heat capacity of a substance is the quantity of energy needed to change the temperature of 1kg of the substance by 1°c” but when a certain mass of a substance is change from solid to. The latent heat of fusion is much less than that of condensation and evaporation however, each in its own way plays an important role in aviation weather as air becomes saturated, water vapor begins to condense on the nearest available surface what surfaces are in the atmosphere on which water vapor may condense. This is called latent heat—the heat required to change water from one phase to another at higher elevations (lower atmospheric pressure) water’s boiling at higher elevations (lower atmospheric pressure) water’s boiling.

In this experiment, the heat of fusion of ice will be determined by using the method of mixtures (quantity of heat lost = quantity of heat gained) introduction when a substance changes phase, that is it goes from either a solid to a liquid or liquid to gas, the energy, it requires energy to do so the potential energy stored in the interatomic. Introduction to hydrology and the water balance the science of hydrology the science that describes and predicts the occurrence, circulation and distribution of the earth’s water there are two principal foci: • the global hydrologic cycle: transfers of water between the land, ocean and atmosphere • the land phase of the hydrologic. The specific latent heat of fusion is 334000 j/kg then process (3): the ice now becomes the water and we need to increase the temperature of the water from 0 to the final temperature the heat required to increase the temperature of the water is determined by the specific heat of the water (the mass of the water is equal to the.
