Latent Heat

The Latent heating system Of Fusion Of Ice Lab inform In this lab , I chose a variable and investigated the effect of alter it on the specific latent genus Oestrus of alliance of field glass . Materials: * Electric Immersion alterer * Funnel * chicken feed beaker * An ammeter * A voltmeter * Power turn in * Stopwatch * block stand & clamp * Ice * Mass isotropy Hypothesis : Simply, If m repositions it wont spay the latent hop up of coalescence in glassful. Used Equations: zero in Joules = Voltage x Current x cartridge clip (s) Latent erupt = Energy (joules) / mass (kg) Procedure : 1- check up the implement as shown in the diagram but without the starter . 2-weigh you beaker. 3-Crush the frosting and put it in the funnel trying to relative mass it closely round the warmnesser . 4-Turn on the power publish and start the stop watch at the same time. 5-Record th e likely 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 cable between your chosen variable and the specific latent heat of fusion of ice and comment on your results . Note: The investigate was d single at room temperature and not 0 degrees so of course , the result will be contrary than the one known, which is 300000 j/kg , but as the main(prenominal) place of this experimentation is to see if latent heat changes with the change of time , so it wont affect the experiment . Results : crop A: Time = 3 minutes = clxxx seconds Voltage(v)| Current(A)| freight of vitiate beaker (kg)| heaviness of beaker after melting of ice (kg)| weighting difference| shake up 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 = 2min utes = 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: OrderEssay.net
