As an athlete exercises, sweat is produced and evaporated to jelp maintain a proper body temperature. On average, an athlete loses approximately 575 g of sweat during and hour of exercise. How much energy is needed to evaporate the sweat that is produced? The heat of vaporization for water is 2257 J/g.

Evaporating sweat cools the body because evaporation is endothermic and absorbs 2.44 kJ per gram of water evaporated. Estimate the mass of water that must evaporate from the skin to cool a body by 0.40 ∘C, if the mass of the body is 99 kg and its heat capacity is 4.0 J/g∘C. (Assume that the heat transfer is 100 % efficient.)

If the air temperature is the same as the temperature of your skin (about 30.0 oC), your body cannot get rid of heat by transferring it to the air. In that case, it gets rid of the heat by evaporating water (sweat). During bicycling, a typical 70.0kg person's body produces energy at a rate of about 53.6 W due to metabolism, 80.0% of which is converted to heat. How many kilograms of water must the person's body evaporate in an...

The average human produces about 15 g of sweat per minute during intense activities. a. If a jogger runs for 30 mins and evaporates all of the sweat he produces after his run, how much heat was transferred from his body to the sweat? Assume the jogger is always seating, the sweat’s initial temperature is 37°C, and that sweat has the same specific heat and latent heat as water. b. A heat stroke occurs when a human’s body temperature reaches...

Each pound of fat contains 3500 food calories. When the body metabolizes food, 80.5% of this energy goes to heat. Suppose you decide to run without stopping, an activity that produces 1340 W of metabolic power for a typical person. Part A) For how many hours must you run to burn up 1 lb of fat? Part B) If you followed your planned exercise program, how much heat would your body produce when you burn up a pound of fat?...

3. 18 points] Warm-blooded animals use large quantities of energy to maintain body temperature because of heat loss through the body surface. In fact, biologists believe that the primary energy drain on a resting warm-blooded energy available is proportional to the blood flow through the lungs, which is circulated, trhe amount of available energy will equal the amount of energy weights of some mammals to their heart rate in beats per minute. Based on weight. Discuss the assumptions of your...

(33%) Problem 3: Warm blooded animals are homeothermic that is, they maintain an approximately constant body temperature. (For humans it's about 37°C.) When they are in an environment that is below their optimum temperature, they use energy derived from chemical reactions within their bodies to warm them up. One of the ways that animals lose energy to their environment is through radiation. Every object emits electromagnetic radiation that depends on its temperature. For very hot objects like the sun, that...
