At a fabrication plant, a hot metal forging has a mass of 66.8 kg and a specific heat capacity of 437 J/(kg C°). To harden it, the forging is quenched by immersion in 785 kg of oil that has a temperature of 25.0 °C and a specific heat capacity of 2770 J/(kg C°). The final temperature of the oil and forging at thermal equilibrium is 61.7 °C. Assuming that heat flows only between the forging and the oil, determine the initial temperature in degrees Celsius of the forging.
