Lab: Specific heat capacity.

Aim: i)         To find the relationship betwixt supplied energy and change in temperature of irrigate. ii)         To find the specific set off capacity (SHC) of piss. Hypothesis: As time increases so does the temperature since the peeing is exposed to the inciteed wire for a longer period of time. Variables: The issuing Variable is the temperature of the water supply, and since the competency is calculated using temperature it is a leechlike variable as well. The ceaseless variables are the potentiality and up-to-the-minute. Theory:          pushing Supplied by Heater = nil Received by peeing Materials:         200ml beaker                           Connecting Wires                  Thermometer         200ml water                           Voltmeter                           Electronic scale         NiCr-Wire                           Ampmeter                           DC spot Supply         Crocodile Clips                  Stopwatch Instructions: i)         Assemble the apparatus as shown in the diagram. You need to take a crap your immersion fastball by winding the NiCr-wire around a pencil say 8 to 10 times. ii)         Take counterbalance measurements of the water incl. its mass and its fall guy temperature. iii)         Place the immersion sens into the water and turn on the power supply. Adjust the voltage across the immersion slug around 12 to 15 volts.

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