Lab: Specific heat capacity.

Aim: i)         To find the relationship in the midst of supplied energy and change in temperature of irrigate. ii)         To find the specific fondness capacity (SHC) of piss. Hypothesis: As time increases so does the temperature since the water system supply is exposed to the heat uped wire for a longer period of time. Variables: The surmount Variable is the temperature of the water, and since the competency is reason using temperature it is a babelike variable as well. The continual variables are the potency and up-to-the-minute. Theory:          ability Supplied by Heater = null Received by piss Materials:         200ml beaker                           Connecting Wires                  Thermometer         200ml water                           Voltmeter                           Electronic scale         NiCr-Wire                           Ampmeter                           DC authority Supply         Crocodile Clips                  Stopwatch Instructions: i)         Assemble the apparatus as shown in the diagram. You need to digit your immersion fastball by winding the NiCr-wire around a pencil say 8 to 10 times. ii)         Take commencement measurements of the water incl. its mass and its menage temperature. iii)         Place the immersion weed into the water and turn on the power supply. Adjust the voltage across the immersion weed around 12 to 15 volts.

iv)         Measure and record time, voltage, modern and temperature at regular intervals in a sui flurry dodge (include uncertainties) v)         Draw a satisfactory graph that will salve you to find the specific heat capacity of the water. vi)         Compare your findings with genuine values for water. Observations: One can reveal the process of diffusion and the water changes its color, from clear to a yellowed solution. On one of the poles atomic number 28 starts to accumulate (Electrolysis). Results: Mass of Beaker = 205,23 g (0.205 kg) Mass of Beaker + pissing = 391,41 g (0.391 kg) Mass of Water = 186,18 g (0.186 kg) Specific Heat Capacity of Water (15?C) =...
