Humans perspire as a way of keeping their bodies from overheating during strenuous exercise. The evapouration of perspiration transfers heat from the body to the surrounding atmosphere. Calculate the total ΔS for evapouration of 1.96 g of water if the skin is at 37.5 oC and the air temperature is 25.2 oC.

    3. [10pts] Since we humans are largely made of water, our bodies are efficient at absorbing cosmic microwave photons. Assume that you absorb all incident CMB photons. Heat ca- - 2- pacity of water is C = 4200 J kg-1 K-1. You may assume you weigh 100 kg and span a spherical volume of 1 m3 for simplicity. Clearly explain your line of logic. (a) Estimate the average number of CMB photons in a 1 m3 volume today. (b) Estimate...
