Unformatted text preview: this situation, we know the physical limit of the temperature of the coffee is room temperature,11 and the differential equation which gives rise to our formula for T (t) takes this into account. Whereas the radioactive decay 10 The time it takes for half of the substance to decay. The Second Law of Thermodynamics states that heat can spontaneously flow from a hotter object to a colder one, but not the other way around. Thus, the coffee could not continue to release heat into the air so as to cool below room temperature. 11 6.5 Applications of Exponential and Logarithmic Functions 383 model had a rate of decay at time t directly proportional to the amount of the element which remained at time t, Newton’s Law of Cooling states that the rate of cooling of the coffee at a given time t is directly proportional to how much of a temperature gap exists between the coffee at time t and room temperature, not the temperature of the coffee itself. In other words, the coffee cools faster when it is first s...
