Question 1

what is the required practical for specific heat capacity?

Answer 1

-measure the mass of a metal block
-insert an immersion heater, and connect it to a power supply, with a joule-meter in between
-insert a thermometer and insulate the block
-record the initial temperature
-turn the power of ams measure the highest temperature
-joule-meter tells us the energy transferred
