### A2/ Expt /Thermal /Kevin/ Carl

1. 1. Specific latent heat of fusion of ice Kevin Carl
2. 2. Diagram and set of equipments
3. 3. Steps to be followed <ul><li>Set up the apparatus as shown in the diagram. </li></ul><ul><li>Measure the mass of the ice. </li></ul><ul><li>Switch on the heater allow it to heat up so that it is slightly warm to the touch and then put it in the ice . </li></ul><ul><li>Record the time (T) when the ice is melted completely. </li></ul><ul><li>Record the voltage (V) and current (I), this may need to be adjusted throughout the experiment so that the power input remains constant. </li></ul><ul><li>Repeat the experiment with a different mass of ice and obtain at least six sets of values </li></ul>
4. 4. Method to collect data(table)
5. 5. Safety measures <ul><li>Caution!!! The electrical heater is likely to be very hot. Handle with care. </li></ul><ul><li>Caution!!! The ice is likely to be very cold. Handle with care. </li></ul><ul><li>Caution!!! T h e voltage of the electrical heater is likely to be high. Handle with care. </li></ul>
6. 6. Method to reduce random error <ul><li>Repeat the experiment for at least 6 times </li></ul><ul><li>Large mass of ice </li></ul><ul><li>Keep the room temperature as low as possible </li></ul><ul><li>Use advanced equipments (voltmeter, ammeter) </li></ul>
