Problem 12.88 Part A 0 g of aluminum at 200 °C and 20 g of copper are dropped into 43 cm3 of ethyl alcohol at 15 °C. The temperature quickly comes to 24 °C What was the initial temperature of the copper? Express your answer using two significant figures.
10.0 g of aluminum at 2.00 × 102 °C and 20.0 g of copper are placed into a well-insulated container with 50.0 cm3 of ethanol at 21.0 °C. The combined system reaches an equilibrium temperature of 25.0 °C. Assume the temperature changes in the container itself can be safely ignored. What was the initial temperature of the copper?
