PROCEDURE Use the 100 mL graduated cylinder to measure and pour 70 mL of room-temperature tap water into a dry StyrofoamTM cup. Record the exact volume in Table 2 on the Experiment 1 Data Sheet. Place the filled cup inside the second cup to increase the insulation temperature. Place and hold the thermometer in the center of the water. Use a timer to time 30 seconds, then measure the initial temperature of the water (Figure 4). Record the value in...
