To better understand our setup, we shall do the first part without any metal at all, but just cold and hot water. Please perform the following steps. QUESTION 1: Measure the mass of the inner cup of the calorimeter. Make sure it's empty and dry. Mass of inner cup: moup = 62 grams. Zero the digital scale, and then place by the calorimeter (both cups + the ring + one thermometer) on top of the digital scale. QUESTION 2: Measure the mass the whole calorimeter. Make sure it's empty and dry. Total mass calorimeter: 241 grams Fill the inner cup of the calorimeter with 150 ml of cold water (from the tap in the lab). QUESTION 3: Measure the mass of the calorimeter + the cold water. Total mass calorimeter + cold water: 392 grams. QUESTION 4: What is the mass of the cool water? Mass of the cold water: moool water = Now it's time to prepare the hot water. Take the 250 ml glass beaker.
