2
Q
Equipment
A
Thermometer
Stopclock
Ammeter
Voltmeter
Mass balance
Pipette
Copper, iron and aluminium block

3
Q
Ammeter purpose
A
The current does work on the heater, so it transfers energy electrically from the power supply to the heater’s thermal energy store by heating, causing the material’s temperature to increase
4
Q
Voltmeter purpose
A
To measure the potential difference
5
Q
Why are scientists interested in finding the specific heat capacity of different objects?
A
Has importance in terms of energy, time and costs involved in changing temperatures of objects
6
Q
Independent variable
A
Time
