Worked example: Measuring enthalpy of reaction using coffee-cup calorimetry

WebNext, we add our two solutions to our calorimeter which has made of two coffee cups. And since the top coffee cup is loose fitting, this reaction is under the constant pressure of the atmosphere. So this is constant pressure calorimetry. After the two aqueous solutions mix, the reaction occurs and we watch the thermometer in the calorimeter. WebJun 4, 2024 · Case 1: Calorimeter made of material with low specific heat. If the calorimeter had a low specific heat, it would absorb less heat, but its temperature would increase more. Differences in temperature cause heat transfer, so a larger difference in temperature between the calorimeter and the surrounding air would mean more heat transfer from the ...
