Calculate the amount of ice that would be melted by a 65 w heater in five minutes at 0 o c if all other heat energy exchanges are ignored specific latent heat of fusion of ice = 330 000 jkg-1 electrical energy input = 65x5x60 = 19500 j mass of ice melted. Use a low specific heat capacity thermometer to ensure minimal energy is removed from the water in order to raise the length of the column of liquid use a digital thermometer correct to 2 decimal places. The heat of fusion, also known as the latent heat of fusion, is a category of latent heat describing the energy for the phase change between a liquid and a solid to occur without a change in temperature to fully grasp this concept, let's first review latent heat.
The prevalent experiments are these two: the specific heat, c, of an unknown metal and the latent heat of fusion (solidification), lf, of water into ice instead of duplicating those standard experiments, we will attempt to try and find a more unusual constant: the. In this experiment the heat given out by the calorimeter, stirrer and water in cooling from the initial to the final temperature is equal to the heat received by the ice ow the ice may be regarded as receiving two lots of heat first, the latent heat necessary to melt it to. 2015/3/19 ice is melted using warm water qice = qh2o can be used to determine the enthalpy of fusion of ice in j/g data is listed at the end of the video qice = qh2o can be used to determine the enthalpy of fusion of ice in.
From this equation you can calculate the specific latent heat of fusion of ice the accepted value is 334,000 j/kg try to explain why your experiment gave a different answer were your 2 results very different. Latent heat of fusion goal: to measure the latent heat of fusion for water lab preparation in this lab you will mix some ice and water and allow them to come to thermal equilibrium, thus review of calorimetry problems that include phase changes is. Using ice and hot water, design an experiment to determine the latent heat of fusion for water there is more than one way here are two possibilities there is more than one way here are two possibilities.
