A constant-flow calorimeter is used to measure the specific heat capacity of a liquid. Two sets of readings are taken at different flow rates and heater powers, and then subtracted to eliminate an unknown heat loss term. Which quantity must be the same in both sets of readings for this method to be valid?
- The rate of heat loss to the surroundings
- The flow rate of the liquid
- The power supplied by the heater
- The inlet temperature of the liquid
