Q
Explain the SHC required practical
A
1) Measure the mass of the block then wrap it with an insulating layer to reduce the energy transferred from block to surroundings .
2) Measure the initial temperature of the block and set the potential difference of the power supply to 10 volts . Switch it on and start the stop watch
3) As the block heats up take readings of the temprature and current every minute for 10 minutes . The reading from the current through the circuit should not change
4) when you have collected enough readings turn off the power supply
5) if you assume all the energy supplied to the heater has been transferred to the block then you can plot a graph of energy transferred against the temprature
