Humans and warm-blooded animals maintain a constant body temperature, which is typically higher than their environment.

A. Estimate the maximum efficiency of a thermodynamic engine that is powered by this temperature difference in moderate climate conditions (the living organism is the hot reservoir and the environment is the cold reservoir). Take the temperature of the human body about 37∘C and assume a temperature of 8 ∘C for the environment.

B. Determine the output power of such an engine if the rate at which the energy is transferred from the living organism to the engine is 100 W.

    (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...

    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...

    A poikilotherm is an organism whose internal temperature varies based upon its environment - it regulates body temperature by basking or burrowing, for example a wood frog. In contrast, mammals are homeotherms, organisms which maintain thermal homeostasis. Both humans and frogs share similar enzymes. Say a metabolic reaction takes the form A → B. Its standard transformed free energy change (ΔG°) is 4.1 kJ mol-1 . (R = 8.3145 J K-1 mol-1 ). Calculate the equilibrium constant for the reaction...
