Solutions volumes should be carefully measured with a graduated cylinder Add solution completely to a dry calorimeter Dont forget to add the spin bar each time Set up the calorimeter with the thermometer 0 to 50C graduated every 01C supported from a stand so that the bulb does not touch the bottom of the cup Note that the thermometer used for calorimetry differs from the less accurate one in your glassware drawer Clamp the calorimeter so that it rests on the stirrer Be careful not to turn on the heat or you will melt the Styrofoam
