Problem: A block of copper of unknown mass has an initial temperature of 65.4 °C. The copper is immersed in a beaker containing 95.7 g of water at 22.7 °C. When the two substances reach thermal equilibrium, the final temperature of both substances is 24.2 °C. What is the mass of the copper block?
[Specific heats: copper = 0.385 J/(g·°C), water = 4.184 J/(g·°C)]
Which chemical equation best illustrates the Law of Conservation of Mass?
