1.Determine the specific heat of lead weighing 49.51 grams when it is initially at 100 °C and is transferred to 50 mL water at 24.4 °C. When temperature stabilizes the final temperature of the system is 27.2 °C.
2. Determine the specific heat of a metal using experimental data from a coffee cup calorimeter: Mass of empty cup 2.31 g Mass of cup + water 180.89 g Mass of cup + water + metal 780.89 g Initial temperature of water 17.0 °C Initial temperature of metal 52.0 °C Final temperature of system 27.0 °C 3. What would the final water temperature be if 80.0 grams of water at 25°C is combined with 60.0 grams of water at 70°C? 4. What would the final water temperature be if 100.0 grams of water at 15°C is combined with 50.0 grams of water at 90°C ? 5. What would the final water temperature be if 20.0 grams of water at 45°C is combined with 25.0 grams of water at 70°C ?
