4. A cup of coffee at temperature P cools at a rate proportional to the difference between its temperature and the surrounding temperature Po. Show that P = the cooling rate constant and A is the integral constant. A cup of coffee at 80°C is left in Ae-kt + Po , where k is a room at 20°C a) Find the cooling equation. b) It is found that after 20 minutes in the room, the temperature of the coffee has decrease by 20°C. Determine the temperature after 30 minutes
