1. using your knowledge of cellular respiration, account for any differences in the amount of work done by the muscles during the exercises (squats, push ups, mountain climbers). think about the organelle where cellular respiration takes place and the composition of muscle tissue.

2. describe any differences in your fine motor skills before muscle fatigue and after muscle fatigue.

The respiratory system removes oxygen and water from the body. select the best answer from the choices provided t f

As part of an industrial process, air as an ideal gas at 10 bar, 400k expands at steady state through a valve to a pressure of 4 bar. the mass flow rate of air is 0.5 kg/s. the air then passes through a heat exchanger where it is cooled to a temperature of 295k with negligible change in pressure. the valve can be modeled as a throttling process, and kinetic and potential energy effects can be neglected. (a) for a control volume enclosing the valve and heat exchanger and enough of the local surroundings that the heat transfer occurs at the ambient temperature of 295 k, determine the rate of entropy production, in kw/k. (b) if the expansion valve were replaced by an adiabatic turbine operating isentropically, what would be the entropy production? compare the results of parts (a) and (b) and discuss.
