P2 - Energy Transfer By Heating Flashcards
P2 - what is the definition for specific heat capacity?
The amount of energy needed to raise the temperature of one kg of a substance by 1 degree celsuis
P2 - Plan an experiment to investigate the specific heat capacity of a metal block.
Measure the mass of the block in kg.
Place a heater in the larger hole in the block.
Connect the ammeter, power pack and heater in series.
Connect the voltmeter in parallel.
Use the pipette to put a small amount of water in the smaller hole.
Put the thermometer in this hole.
Switch the power pack to 12 V. Switch it on.
Record the ammeter and voltmeter readings. (These shouldn’t change during the experiment).
Measure the temperature and switch on the stop clock.
Record the temperature every minute for 10 minutes.
