Specific heat capacity of solids: The practicum determines the specific heat of solid objects by measuring temperature changes during heat exchange between a heated solid and a cooler water (ice-water) environment.
Heat transfer and thermal equilibrium:
- Measuring the maximum (final) temperature after the solid is placed into the calorimeter.
- Controlling conditions such as a constant heater temperature and cooling the distilled water to below room temperature before mixing.
Calorimetry: Using a calorimeter equipped with stirring and thermometry to measure heat changes between a solid sample and water.
Cooling with ice water: Distilled water is cooled in an ice-water bath to reach temperatures below room temperature prior to the experiment.

Weigh the solid object to be tested and record its mass.
Heat the solid (using the heater) and measure its temperature with a thermometer until it becomes constant.
Weigh distilled water (zero the balance first) and add it to a predetermined mass.
Place the weighed distilled water into a basin of ice water and cool it until its temperature is below room temperature.
Ensure:
- The heater temperature is constant
- The distilled water in the cooling tub is below room temperature
Weigh the calorimeter and stirrer, and record their values.
Assemble the calorimeter and open its cover.
Quickly place the solid into the calorimeter, then close it.
Insert the thermometer, stir, and record the maximum temperature (final temperature).
Repeat the same steps for the second solid object.
