During a bout with the flu an 80 kg man ran a fever of 39.0°C (102.2°F) instead of the normal body temperature of 37.0°C (98.6°F). Assuming that the human body is mostly water, how much heat is required to raise his temperature by that amount? IDENTIFY and SET UP This problem uses the relationship among heat (the target variable), mass, specific heat, and tem- perature change. We use Eq. (17.13) to determine the required heat Q. with m = 80 kg. c = 4190 J/kg K (for water), and AT = 39.0°C - 37.0°C = 2.0 C = 2.0 K. EXECUTE From Eq. (17.13), Q = mc AT = (80 kg)(4190 J/kg · K)(2.0 K) = 6.7 x 10°J If the person in the example above is a Terminator machine that is composed of 99.99% Aluminum. How much energy is required to raise his temperature on the said problem?

To treat a burn on his hand, a person decides to place an ice cube on the burned skin. The mass of the ice cube is 16.8 g, and its initial temperature is -10.7 °C. The water resulting from the melted ice reaches the temperature of his skin, 29.4 'C. How much heat is absorbed by the ice cube and resulting water? Assume that all of the water remains in the hand. Constants for water can be found in this table.
