At a fabrication plant, a hot metal forging has a mass of 78 kg and a specific heat capacity of 430J/(kg·°C). To harden it, the forging is immersed in 710kg of oil that has a temperature of 32°C and a specific heat capacity of 3000 J/(kg·°C). The final temperature of the oil and forging at thermal equilibrium is47° C. Assuming that heat flows only among the forging and the oil, decide the initial temperature of the forging.
