7. Your coffee mug (r = 5cm, h = 10 cm) is sitting on your table. The coffee and mug are at a temperature of 70°C. Assuming that radiation absorbed by the mug from the environment is negligible. The density of the mug and coffee p= 1 g/cm and its heat capacity Cp = 4j/g/°C. . a) What is the rate of energy loss from the mug at initial time? b) How fast is the coffee cooling at its time by radiation alone? c) At that rate of energy loss, how long would it take to coffee to cool to room temperature, 25 °C.
