A cube of ice is taken from the freezer at -8.5°C and placed in a 100 gram aluminumcalorimeter filled with 300 grams of water at a room temperature of 20°C. The final situationis observed to be all water at 17°C. What was the mass of the ice cube? Given the followingvalues: Cice =2100 J/kg/°C, Cwater = 4186 J/kg/°C, Caluminum 920 J/kg/°C, and for waterLe 3.33×105 J/kg and Lv = 22.6×105 J/kg.1

The American Burn Association states 3. You heat up an aluminum sphere of radius r, 1.27254 cm to 100 °C. You cool a 20.0 g copper ring to 0.00000 °C. The inner radius of the copper ring is r, 1.27000 cm. You then place the sphere on top of the ring and they are allowed to reach thermal equilibrium. Assume no heat loss to the surroundings. At the equilibrium temperature the sphere falls through the ring. (a) What is the thermal equilibrium temperature? (b) What was the amount of heat that was transferred between the ring and the sphere? (e) Which object lost the heat and which object gained the heat? (d) What is the mass of the aluminum sphere? Do not use the definition of density to solve for the mass. O

A 40 g block of ice is cooled to -76°C and is then added to 610 g of water in an 80 g copper calorimeter at a temperature of 27°C. Determine the final temperature of the system consisting of the ice, water, and calorimeter. Remember that the ice must first warm to 0°C, melt, and then continue warming as water. The specific heat of ice is 0.500 cal/g ·°C = 2090 J/kg°C.
