Part A A 33 gram sample of copper (Csp(Cu) = 0.385 J/g K) is placed in a constant-pressure calorimeter containing 100 g of liquid water at 99.5C right below the boiling temperature of 99.6C. After some time the temperature of the water becomes constant at 92.3C. What was the initial temperature of the copper block? Assume no heat is lost to the surroundings. absorbs energy, and it is negative if the system releases energy (Figure 1) The total change in internal energy is the sum of the heat, q, and work w. AU = 9+w. Classify the following by the sign of AU for the system, Drag the appropriate items to their respective bins. If no definitive classification can item into the bin labeled "Not enough data."
