Lab: Specific heat capacity.

Aim: i)         To find the relationship between supplied energy and change in temperature of irrigate. ii)         To find the specific screw up capacity (SHC) of piss. Hypothesis: As time increases so does the temperature since the weewee system is exposed to the heat energyed wire for a longer period of time. Variables: The overthrow Variable is the temperature of the water, and since the competency is calculated using temperature it is a dependant variable as well. The unalterable variables are the emf and up-to-the-minute. Theory:          thrust Supplied by Heater = competency Received by piss Materials:         200ml beaker                           Connecting Wires                  Thermometer         200ml water                           Voltmeter                           Electronic scale         NiCr-Wire                           Ampmeter                           DC advocate Supply         Crocodile Clips                  Stopwatch Instructions: i)         Assemble the apparatus as shown in the diagram. You need to take in your immersion fastball by winding the NiCr-wire around a pencil say 8 to 10 times. ii)         Take head start measurements of the water incl. its mass and its mug temperature. iii)         Place the immersion fume into the water and turn on the power supply. Adjust the voltage across the immersion pot around 12 to 15 volts.

iv)         Measure and record time, voltage, live and temperature at regular intervals in a sui flurry bow (include uncertainties) v)         Draw a adapted graph that will clean-cut you to find the specific heat capacity of the water. vi)         Compare your findings with genuine values for water. Observations: One can follow the process of diffusion and the water changes its color, from clear to a yellowish solution. On one of the poles plate starts to accumulate (Electrolysis). Results: Mass of Beaker = 205,23 g (0.205 kg) Mass of Beaker + pee = 391,41 g (0.391 kg) Mass of Water = 186,18 g (0.186 kg) Specific Heat Capacity of Water (15?C) =...
