How Much Will The Coffee Temperature Decrease When The Milk Is Added?

Coffee works in a way that is beyond words could describe from the way it is brewed to the way it is taken and with which company. There is something that is observed when the coffee is on the table or adding flavor and milk to it. A good example is when you add milk to coffee it decreases its temperature. Why? Well, the rate at which the heat is lost in coffee is proportional to the difference in temperature in coffee and the room temperature.

It is quite reasonable that when you take two cups of coffee and add cold milk to one of them, the temperature of the one you have added milk will decrease to a temperature between the hot coffee and the cold milk.  But what you have to know is that it has been proven that hot coffee has a slower cooling rate when you add creamy milk. As we have said above, things tend to cool faster when the temperature is compared to that of the room temperature. 

The reason why the temperature decreased from the coffee after adding milk to it was that the fat in the milk melted and evaporated leading to loss of heat. When the temperature decrease from the coffee, there is much difference between the room temperature and its own temperature.

When you place a hot coffee on the table without milk, you will notice that the coffee is hotter than the room temperature. Even when you add milk to it, it just lightens the color of the coffee. Immediately the black coffee is added milk to it. It start to lose temperature at a much faster rate. If you compare with the black coffee without milk, you will see the differences very clearly as the black coffee will remain hot for a while longer. 

But all this also depends on the type of milk you have added to it. If it is creamy and fatty milk, it lessons from the evaporation at the surface of the coffee to leave a less heated coffee. When you look at this you will come to know why the coffee with full of cream milk is able to contain its heat much longer than with no milk or with skim milk since they have no fat or even if they do, it id little to hold the heat
