Problem 20DQ

A person pours a cup of hot coffee, intending to drink it five minutes later. To keep the coffee as hot as possible, should she put cream in it now or wait until just before she drinks it? Explain.

Step-by-Step Solution:
Step 1 of 3

Solution 20DQ Heat is a form of energy. Heat always transfers hot body to cold body.In this case the person have to wait because coffee is already being exposed to many cooling factors before you drink it. The cup you are pouring it into cools it initially, followed by the air temperature while in transit. The best thing to do is seal the coffee in in insulated cup and add cream only when you're ready to enjoy it.
