4. Calorimetry can be used to determine the specific heat capacity of different substances (not just metals). Using the online calorimeter simulation you perform the following calorimetry experiment: 100g of ethanol at 50.0°C is mixed with 100. g of water at 20.0°C. After mixing the temperature is 31.11°C. Calculate the specific heat capacity of ethanol.

In problem #4 you calculated the specific heat capacity of ethanol from data obtained using the online calorimeter simulation. When you try the same experiment in a real calorimeter, the final temperature after mixing is 34.00°C. Offer an explanation for why the final temperatures are different. Hint: the calorimeter simulation may be missing something.
