7. A 50.0 g sample of metal at 100.0 °C is placed in a coffee-cup calorimeter containing 100.0 g of water at 25.0 °C. The final temperature of the water and metal is 28.5 °C. Assuming no heat loss to the surroundings and the specific heat capacity of water is 4.18 J/g°C, calculate the specific heat capacity of the metal.
8. A bomb calorimeter is primarily used to measure the heat of combustion at constant volume.
