You would like to drink a cup of very hot coffee with milk early in the morning, but you
are in a hurry and have only 5 minutes until you have to leave for work. At which time
after brewing should you add the cold milk to the coffee and stir in order to decrease the
temperature of the mixture as much as possible:
a) 0 minutes (immediately),
b) 2 minutes, or
c) 4 minutes?
Suppose that the stirring can be done instantaneously and that you need the last one
minute for drinking.

brew temperature C = 80 ◦C, temperature of milk = M = 10 ◦C, room temperature
0 = 20 ◦C, volume of coffee VC = 300 ml, volume of milk VM = 100 ml, specific heat
capacity of coffee cC = 4180 J/(kgK), specific heat capacity of milk cM = 3500 J/(kgK).

Please enter only the letter of the corresponding answer

a. 2 mins

b. 0 mins

c. 4 mins

The driving „force“ for the cooling of the coffee is the temperature difference between the warm coffee and the environment (room temperature), which leads to an exponential drop in coffee temperature. The temperature difference is greatest immediately after brewing. The later we stir in the milk, the lower the coffee temperature has already dropped. On the other hand, lowering the temperature by the milk becomes smaller the longer we wait.
So we let the coffee cool down on its own for as long as possible in order to bring about the temperature reduction by the cold milk at the end. The greatest possible cooling is therefore achieved when the milk is added after 4 minutes.
