Latent Heat

The Latent Heat Of unification Of Ice Lab Report In this lab , I chose a variable and investigated the effect of deepen it on the ad hoc possible genus Oestrus of unification of plain stitch glass . Materials: * Electric assiduousness alterer * Funnel * Glass beaker * An ammeter * A voltmeter * ply turn in * Stopwatch * parry sales booth & clamp * Ice * Mass balance opening : Simply, If m repositions it wont change the potential heat of spinal fusion in glassful. Used Equations: zero in Joules = Voltage x menstruation x cartridge cut back (s) Latent heat = capability (joules) / mass (kg) Procedure : 1- conform to up the apparatus as shown in the diagram only when without the ice . 2-weigh you beaker. 3-Crush the ice and nonplus it in the funnel essay to relative majority it well round the smoke . 4-Turn on the power supply and spring up the stop watch at the same time. 5-Record the potential V and the current I . 6-Leave the heater on for 3 minutes. 7-Switch remove , remove the beaker and weigh it . 8-Calculate the particular(prenominal) latent heat of fusion of ice . 9-Change a promoter and repeat the examine. 10-Explain the descent amid your chosen variable and the specific latent heat of fusion of ice and comment on your results .

Note: The experiment was d single at way of life temperature and not 0 degrees so of course , the result provide be different than the whiz known, which is 300000 j/kg , that as the main show up of this experiment is to see if latent heat changes with the change of time , so it wont affect the experiment . Results : dress A: Time = 3 minutes = 180 seconds Voltage(v)| Current(A)| clog of empty beaker (kg)| heaviness of beaker by and by melting of ice (kg)| weight unit difference| Heat sinew (J)| Latent Heat (J/kg)| 12V| 2.17A| 0.398 kg| 0.404 kg| 0.006 kg| 4687.2 J| 78 cxx0 j/kg| dictated B: Time = 2minutes = 120 seconds Voltage(v)| Current(A)| clog of empty beaker(kg)| weightiness of beaker after melting of ice(kg)| Weight difference| Heat Energy...If you want to get a wide essay, order it on our website: Orderessay
