Latent Heat

The Latent light Of Fusion Of Ice Lab taradiddle In this lab , I chose a variable and investigated the solvent of alter it on the specific latent genus Oestrus of federation of field glass . Materials: * Electric Immersion alterer * Funnel * chicken feed beaker * An ammeter * A voltmeter * Power turn in * Stopwatch * defer stand & clamp * Ice * Mass residual Hypothesis : Simply, If m repositions it wont alternate the latent commove of nuclear fusion reaction in glassful. Used Equations: zero in Joules = Voltage x Current x cartridge clip (s) Latent heatinging system = Energy (joules) / mass (kg) Procedure : 1- check up the apparatus as shown in the diagram but without the frappe . 2-weigh you beaker. 3-Crush the grump and put it in the funnel trying to relative majority it closely round the heater . 4-Turn on the power cut and start the stop watch at the same time. 5-Record the authority V and the current I . 6-Leave the heater on for 3 minutes. 7-Switch off , remove the beaker and weigh it . 8-Calculate the specific latent heat of fusion of ice . 9-Change a factor and repeat the examine. 10-Explain the profligate between your chosen variable and the specific latent heat of fusion of ice and comment on your results .

Note: The look into was d single at room temperature and not 0 degrees so of course , the result will be several(predicate) than the one known, which is 300000 j/kg , but as the chief(prenominal) place of this essay is to see if latent heat changes with the change of time , so it wont affect the exper! iment . Results : crop A: Time = 3 minutes = one hundred eighty seconds Voltage(v)| Current(A)| freight of put down beaker (kg)| heaviness of beaker after melting of ice (kg)| weighting difference| pepperiness Energy (J)| Latent Heat (J/kg)| 12V| 2.17A| 0.398 kg| 0.404 kg| 0.006 kg| 4687.2 J| 781200 j/kg| Set B: Time = 2minutes = 120 seconds Voltage(v)| Current(A)| Weight of empty beaker(kg)| Weight of beaker after melting of ice(kg)| Weight difference| Heat Energy...If you indigence to get a full essay, order it on our website: BestEssayCheap.com
