Assume that the animal's skin temperature is 32.0 , that the air temperature is 5.00 , and that has the same thermal conductivity as air. (b) What food intake will the animal need in one day to replace this heat transfer?(a) Suppose a meter stick made of steel and one made of aluminum ale the same length at 0 C.

The hammer has a speed v=6 m/s just before striking the nail and then come to rest after the impact, see Fig below. Assume that all the energy of the hammer goes into heating the nail during the strike. What is the rise in temperature of the nail?A 25,000 kg subway train initially traveling at 15.5 m/sslows to a stop in a station and then stays there long enough for itsbrakes to cool. The station’s dimensions are 65.0 m long by 20.0 mwide by 12.0 m high. Assuming all the work done by the brakes in stoppingthe train is transferred as heat uniformly to all the air in the station,by how much does the air temperature in the station rise? Take the densityof the air to be 1.20 kg>m3 and its specific heat to be 1020 J /kg . K.200 kg of water at 0o C is in an insulated container. A .500 kg sample of iron (448 J/kg-C) at 100oC is added to the water. What will be the temperature of the system when it reaches thermal equilibrium? You can ignore the reaction of the container.

Ignore any heating by the person's metabolism. The specific heat capacity of a human body is 3480 J/kg⋅KJ/kg⋅K. Is the change in the person's body temperature great enough to be measured by a medical thermometer? (A high-quality medical thermometer can measure temperature changes as small as 0.1∘C∘C or less.)The human body, while at rest, produces heat energy at a rate of about 116 W.

- Digestingfat produces 9.3 food calories per gram of fat, and typically 80%of this energy goes to heat when metabolized. (One food calorie is1000 calories and therefore equals 4186 J.) The body then movesall this heat to the surface by a combination of thermal conductivityand motion of the blood. The internal temperature of the body(where digestion occurs) is normally 37C, and the surface is usuallyabout 30C.
