- A student measures the following data in a calorimetry experiment designed to determine the specific heat of aluminum. (Do not assume atmospheric pressure.) Initial temperature of water and calorimeter: 70°C Mass of water: 0.400 kg Mass of calorimeter: 0.040 kg Specific heat of calorimeter: 0.63 kJ/kg · °c Initial temperature of aluminum: 26.5°C Mass of aluminum: 0.200 kg Final temperature of mixture: 65.9°C Use these data to determine the specific heat of aluminum. J/kg · °CWhat is the ratio of the energy required to warm 125 g of Ice (0.0 \deg C) to body temperature (37 \deg C) to warming the same amount of water through the same temperature change? Answer format is the number Eice/Ewater = (2 significant figures) Latent Heat of Fusion of Water: 335, 000 J/kg Specific Heat Capacity of Water: 4186 J/kg/\deg COne strategy when on a diet is to drink ice water. The body must burn calories to warm the water from 32 °F to a body temperature of 98.6 °F. Assume a dieter drinks 2.4 kg (2.4 L) of ice water every day. How much energy, in Cal, does the dieter's body need to provide in order to warm the 2.4-L-water. (The specific heat of water is 4186 J/kg • °C; 1J = 0.000239 Cal.) Show your work.
