Multiple-Concept Example 8 reviews the approach that is used in problems such as this. A person eats a dessert that contains 160 Calories. (This "Calorie" unit, with a capital C. is the one used by nutritionists: 1 Calorie = 4186 J. See Section 12.7.) The skin temperature of the person is 35 °C and that of her environment is 15 °C. The emissivity of her skin is 0.79 and its surface area is 1.5 m2. How many hours would it take her to emit a net radiant energy from her body that is equal to the energy contained in this dessert?
