Review | Constants Periodic Table Part A Assume you are performing the calibration step of Experiment 8 and you begin with 30 g of water at 20 °C and 30 g of water at 80 °C. After adding the two portions of water into your calorimeter setup and following the procedure outlined in the experiment, you determine the temperature of the mixed portions of water to be 45 °C. What is the heat capacity of the calorimeter? Assume room temperature...
