Complete solution
An iron sphere with a mass of 7.50 g was placed in a boiling water bath
and allowed to sit until thermal equilibrium is achieved. Eventually, the
hot iron sphere was immersed into a room temperature (about 22
degrees Celsius) water with a mass of 25.0 g. Calculate the final
temperature of the water/iron system. The heat capacities of water
and iron are 4.18 J/gK and 0.452 J/gK.
