In a 25°C room, hot coffee in a vacuum flask cools from 75°C to 50°C in 8 hours. Explain why you predict that its temperature after another 8 hours will be 37.5°C.

Solution 3P This question can be solved using Newton’s law of cooling. This law states that the rate of change of temperature of a body is proportional to the temperature difference between the body and its surrounding. dT It can be written as, dt = k(T tT ) …1.(1) Here, dT = temperature change dt = change of time k = constant of proportionality T =...
