Multiple-Concept Example 8 reviews the approach that is used in problems such as this. A person eats a dessert that contains 240 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 38 °C and that of her environment is 18 °C. The emissivity of her skin is 0.68 and its surface area is 1.3 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? Heat from environment Number Units Heat from person Το T
