A student sets up an experiment to determine the specific heat capacity of a metal block using an electrical heater.
Which piece of apparatus can be omitted if the objective of the experiment is to determine the thermal capacity (heat capacity) of the metal block instead of its specific heat capacity?
balance
ammeter
stop-clock
thermometer
