Experiment 2: The following data is required; Mass of aluiminium cup: 28 g Mass of cup plus water: 75 g Initial water temperature: 23 OC Initial propylene glycol temperature: 80 oC Final temperature of solution: 41 oC Volume of propylene glycol added: 15 mL Using this data you can determine the total energy transferred from the propylene glycol to the water and cup. This value of Q can also be used to determine the value of the heat capacity for propylene glycol. The one additional step required here is to determine the mass of propylene glycol. Note I have provided the density of propylene glycol on the worksheet. Experiment 2: Specific heat capacity of propylene glycol In this experiment we will measure the temperature change in a mixture of water and propylene glycol to determine heat capacity. 1. Place a bottle of propylene glycol in the water bath at a temperature of 80 °C. 2. Clean and dry the aluminium cup from the calorimeter, and re-weigh. 3. Measure approximately 40 mL of room temperature water and add to the aluminium cup. 4. Measure the temperature of the water. 5. Carefully measure 15 mL of heated propylene glycol and add to the aluminium cup. 6. Add the cup to the calorimeter, and gently swirl, measuring the temperature every 5 seconds. 7. Continue to measure until a maximum temperature is reached. Values needed for calculations; Specific Heat Capacity of Water: 4.184 J.g-1K-1 Specific Heat Capacity of Aluminium: 0.91 J.g-1K-1 Density of propylene glycol: 1004 kg.m-3 Please calculate the following: 1. Determine the temperature change of the cup and the water. 2. Determine the temperature change in the propylene glycol. 3. Calculate the total heat transfer to the cup and the water. 4. Calculate the mass of propylene glycol (change to grams) 5. Using the value of heat transfer calculated in question 3 to determine the heat capacity of propylene glycol.
