Transcribed Image Text:**Heat Treating Process Problem**
In a heat-treating process, a metal part weighing 1 kg, initially at a temperature of 1000 K, is quenched in a closed tank containing 100 kg of water initially at 295 K. There is negligible heat transfer between the contents of the tank and their surroundings.
The metal part and water are modeled as incompressible substances with constant specific heats of 0.5 kJ/kg·K for the metal and 4.4 kJ/kg·K for the water. The task is to determine the final equilibrium temperature after quenching, expressed in Kelvin.
This problem involves understanding heat transfer principles, specifically requiring application of the conservation of energy to find the equilibrium state of the system.
