5) 0.2 kg of hot coffee at 100.0ºC is added to a sink full of 1.0 kg of water at 20.0ºC. The specific heat for coffee is basically the same as for water and is 1.0 cal/g ºC=4186 J/kg ºC. The water-coffee system is otherwise isolated.
A) What temperature does the final mixture come to in equilibrium?
B) How much heat is transferred from the coffee to the water?
