Latent Heat

The Latent Heat Of nuclear optical federation Of Ice Lab Report In this lab , I chose a variable and investigated the effect of neuter it on the peculiar(prenominal) potential genus Oestrus of fusion of bailiwick glass . Materials: * Electric dousing alterer * Funnel * Glass beaker * An ammeter * A voltmeter * superpower turn in * Stopwatch * parry bandstand & clamp * Ice * Mass balance possibility : Simply, If m repositions it wont change the potential heat of fusion in glassful. Used Equations: zero in Joules = Voltage x trustworthy x cartridge break short (s) Latent heat = power (joules) / mass (kg) Procedure : 1- add up the apparatus as shown in the diagram moreover without the ice . 2-weigh you beaker. 3-Crush the ice and vomit up it in the funnel essay to relative majority it closely round the bullet . 4-Turn on the power supply and nonplus the stop watch at the same cartridge holder. 5-Record the potential V and the current I . 6-Leave the heater on for 3 minutes. 7-Switch onward , remove the beaker and weigh it . 8-Calculate the specific potential heat of fusion of ice . 9-Change a means and repeat the examine. 10-Explain the descent betwixt your chosen variable and the specific latent heat of fusion of ice and comment on your results .

Note: The experiment was d single at mode temperature and not 0 degrees so of course , the result pull up stakes be different than the iodin known, which is 300000 j/kg , exactly as the main redact of this experiment is to see if latent heat changes with the change of time , so it wont affect the experiment . Results : decorate A: Time = 3 minutes = 180 seconds Voltage(v)| Current(A)| freight of empty beaker (kg)| heaviness of beaker after melting of ice (kg)| weightiness difference| Heat might (J)| Latent Heat (J/kg)| 12V| 2.17A| 0.398 kg| 0.404 kg| 0.006 kg| 4687.2 J| 78long hundred0 j/kg| come in B: Time = 2minutes = 120 seconds Voltage(v)| Current(A)| weightiness of empty beaker(kg)| weight down of beaker after melting of ice(kg)| Weight difference| Heat Energy...If you pauperization to get a salutary essay, order it on our website: Ordercustompaper.com
