1) An ice cube with a mass of 0.0470 kg at 0°C melts to water with no change in temperature. How much heat does the ice absorb while melting?
2) A large handful of identical gemstones, totaling 195 carats (one carat has a mass of 200 mg) at temperature 73.2°C, is placed in a calorimeter filled with 0.594 kg of water at 13.6°C. After thermal equilibrium is established, the water temperature is 14.1°C. What is the specific heat of the gemstone material?
