Determining the specific heat capacity of a sample can be achieved by cooling it to the temperature of ice, as both the heat of fusion and heat of vaporization are relevant in calorimetry. However, cooling to ice temperature may complicate calculations due to the phase change involved in melting ice. The change in temperature for the sample is calculated as the initial temperature minus the final temperature, which is the temperature of the ice. This method requires careful consideration of the heat transfer processes involved. Overall, while cooling to ice temperature is feasible, it introduces additional complexities compared to heating to boiling point.
