At a fabrication plant, a hot metal forging has a mass of 75 kg and a specific heat
capacity of 430 j/(kg? c°). to harden it, the forging is immersed in 710 kg of oil that has
a temperature of 32 °c and a specific heat capacity of 2700 j/(kg? c°). the final
temperature of the oil and forging at thermal equilibrium is 47 °c. assuming that heat
flows only between the forging and the oil, determine the initial temperature of the
forging.
