The typical diameter of an alveolus is 0.3 mm. the surface tension of water is about 70 dyne/cm. the dyne is the unit of force in the cgs system: 1 g*cm/s2. what is the pressure within this alveolus assuming no surfactant at mechanical equilibrium? give the answer in mm hg. (hint: use law of laplace for a sphere)

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
