So this is the last experiment we had to do: Calorimetry. It was quite simple.
We had two cups made of styrofoam, which were weighed using a digital balance. Then, one cup was 1/3 full of hot water and the other was 1/3 full of cold water. The mass of each cup was measured again. The temperatures of each cup was recorded as Thot and Tcold. Immediately after making measurements, contents of one cup was poured unto the other and Tfinal and Mfinal (mass) was determined. Three trials were done, with masses and temperatures varied.
Using the equations: ΔHhot = (MH2O, hot)(ΔThot)(1cal/g°C), and
ΔHcold = (MH2O, cold)(ΔTcold)(1cal/g°C),
we were able to calculate the amount of heat energy transferred in the setup.
The temperature was observed to reach equilibrium, showing that the warmer system transferred heat to the cooler one and that energy is conserved throughout the process.
This experiment was quite straightforward in the procedure and calculations.
