Calorimetry(determination of specific heat capacity)

AI Thread Summary
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.

can we determine a specific heat of a sample by cooling it to the temperature of ice rather than heating it to the boiling point of water?

why not?we have the"heat of vaporization" but we have the"heat of fusion",too

then, how to calculate the change of temperature of the sample?
is it 0°C minus the final temperature?

Vídeo: The footage was filmed in real time. The rotor takes advantage of the thermal agitation of the water. The agitation is uniform, so the resultant is zero. When the aluminum cylinders containing frozen water are immersed in the water, about 30% of their surface is in contact with the water, and the rest is thermally insulated by styrofoam. This creates an imbalance in the agitation: the cold side of the water "shrinks," so that the hot side pushes the cylinders toward the cold...
