this is a thermodynamics course We want to model energy and mass balance issues involved in strenuous exercise, for example the running of a marathon. Suppose a 70 kg marathon runner runs at an ≈8 minute/mile pace, completing the 26.2 mile race distance in 210 minutes, or 3.5 hours. a.) Physiological measurements indicate that the total power consumed by an average weight runner (70 kg) at a pace of 8 minutes/mile is about 900 kcal/hour. What is the total energy...

Diffusion of gases across a permeable membrane 1. How long did it take the O2 levels to become about equal outside and inside the cell? What happened to those levels after they became about equal over the additional 10 seconds? Why did this happen? My answer: It took 6 seconds to become equal. After they became about equal over the additional 10 seconds they fluctuate back and forth as equal equilibrium is achieved. 2.Cell use O2 and produce CO2 as...
