Could you give me conclusion and do the questions experiment 3 the latent heat of fusion of ice a small amount of ice is placed in a calorimeter containing water. I am doing a lab experiment in school to find the molar enthalpy of fusion of water ice and water are mixed in a calorimeter and the temperatures are recorded here are my results mass of ice cube: 661g mass of water: 100g initial ice temperature: 0 degrees celsius initial water temperature: 21 degrees celsius.
Where c w anf c c are the specific heat capacity of water, resp of the material from which the inner container of the calorimeter is made, and m w a m c is the mass of water, resp of the inner container of the calorimeter. Physics 1030l lab: heat of fusion the ﬂow of heat will be examined in this experiment 1) ice cubes will be placed into a certain amount of water in a styrofoam coffee cup that will be used as the ice melts, and as the melted ice warms, the water and the calorimeter cool the heat lost by the water.
William meighan hour 1 purpose: 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. Extension: design an experiment to find out if an ice cube taken from a freezer and immediately placed into a calorimeter needs the same amount of energy per gram for melting as does an ice cube that has been outside the freezer for 10 minutes.
In this experiment you will try to measure the latent heat of fusion of ice (lhice), the energy needed (per gram) to melt ice the needed energy will come from a cup of warm water the amount of water and its temperature will be measured before adding some ice and then again after the ice has been melted. Psv #8: in this experiment, you will use a calorimeter make temperature measurements analyze the data collected determine heat of fusion for ice (in j/g. Experiment 4-heat of fusion and melting ice experiment in this lab, the heat of fusion for water will be determined by monitoring the temperature changes while a known mass of ice melts in a cup of water.
Calorimetry: heat of fusion of ice unlike most calorimeters, the simple styrofoam-cup calorimeter used in this experiment will have only one chamber the ice will be placed directly into a measured amount mass the calorimeter cup and water at the end of the laboratory exercise. Heat will continue to flow from the warm water into the 0 o c ice water energy will flow until all of the water has the same temperature, tfinal energy will flow until all of the water has the same temperature, tfinal.
Calorimetry lab - specific heat capacity introduction in this experiment, heat is transferred from a hot metal sample to a colder water sample 5 pour 25 ml of tap water into the calorimeter and mass the calorimeter again record this mass in the data table 6.
So if an attempt is being made to determine the specific heat of fusion of ice using a coffee cup calorimeter, then the assumption is that the energy gained by the ice when melting is equal to the energy lost by the surrounding water. I'm taking a first year physics course and our upcoming lab is an experiment to determine the heat of fusion for ice there are a few questions that i have ma is the mass of the reservoir and stirrer (aluminum) c is the speci c heat of water ca is the speci c heat of the (aluminum) reservoir q is.
Experimental determination of specific heat of water experiment number : 1767 if we heat the water using an alternating current, more proficient students can object that intensive stirring of the water in the calorimeter can cause a temperature increase of water, because mechanical work is performed. And any design of a calorimeter experiment must give attention to reducing the exchanges of heat between the calorimeter contents and the surroundings bomb calorimetry the coffee cup calorimeters used in high school science labs provides students with a worthwhile exercise in calorimetry.
