An artist crafting a piece of metal in the forging studio plunges the hot metal into oil in order to harden it. The metal piece has a mass of 56 kg and its specific heat is 429.7 J/(kg · K). The artist uses 810 kg of oil at 35°C, with a specific heat of 2999 J/(kg · K), for the process. Once the metal is immersed in the oil, the temperature reaches an equilibrium value of 41°C. How hot was the forged metal piece just before it was plunged it into the oil?
