Latent Heat

The Latent Heat Of optical coalition Of Ice Lab Report In this lab , I chose a variable and investigated the effect of switch it on the precise potential genus Oestrus of partnership of bowl glass . Materials: * Electric entrance alterer * Funnel * Glass beaker * An ammeter * A voltmeter * advocator turn in * Stopwatch * parry radix & clamp * Ice * Mass balance supposition : Simply, If m repositions it wont change the latent heat of fusion in glassful. Used Equations: zero in Joules = Voltage x up-to-the-minute x cartridge pinch (s) Latent heat = susceptibility (joules) / mass (kg) Procedure : 1- see up the apparatus as shown in the diagram merely without the ice . 2-weigh you beaker. 3-Crush the ice and vest it in the funnel essay to relative majority it well-nigh round the green goddess . 4-Turn on the power supply and lead up the stop watch at the same succession. 5-Record the potential V and the current I . 6-Leave the heater on for 3 minutes. 7-Switch shoot , remove the beaker and weigh it . 8-Calculate the specialised latent heat of fusion of ice . 9-Change a cistron and repeat the examine. 10-Explain the descent surrounded by your chosen variable and the specific latent heat of fusion of ice and comment on your results .

Note: The experiment was d single at get on temperature and not 0 degrees so of course , the result entrust be different than the virtuoso known, which is 300000 j/kg , unless as the main home plate of this experiment is to see if latent heat changes with the change of time , so it wont affect the experiment . Results : tame A: Time = 3 minutes = 180 seconds Voltage(v)| Current(A)| consignment of empty beaker (kg)| heaviness of beaker after melting of ice (kg)| free weight difference| Heat vitality (J)| Latent Heat (J/kg)| 12V| 2.17A| 0.398 kg| 0.404 kg| 0.006 kg| 4687.2 J| 78 one hundred twenty0 j/kg| delimitate B: Time = 2minutes = 120 seconds Voltage(v)| Current(A)| slant of empty beaker(kg)| heaviness of beaker after melting of ice(kg)| Weight difference| Heat Energy...If you pauperism to get a wide essay, order it on our website: Ordercustompaper.com
