Question

Suppose that a cup of coffee begins at 185 degrees and, after sitting in room temperature of 63 degrees for 15 minutes, the coffee reaches 177 degrees. How long will it take before the coffee reaches 162 degrees? Round your answer to 2 decimal places.

Answer 1

To determine how long it will take for the coffee to reach 162 degrees, we need to use the concept of heat transfer. The rate at which an object loses heat is proportional to the temperature difference between the object and its surroundings. This can be expressed using Newton's Law of Cooling Q=k (T-Ts)
