Appendix B lists the vapor pressure of water at various external pressures.
(a) Plot the data in Appendix B, vapor pressure (torr) versus temperature (oC). From your plot, estimate the vapor pressure of water at body temperature, 37 oC.
(b) Explain the significance of the data point at 760.0 torr, 100 oC.
(c) A city at an altitude of 5000 ft above sea level has a barometric pressure of 633 torr. To what temperature would you have to heat water to boil it in this city?
(d) A city at an altitude of 500 ft below sea level would have a barometric pressure of 774 torr. To what temperature would you have to heat water to boil it in this city?
(e) For the two cities in parts (c) and (d), compare the average kinetic energies of the water molecules at their boiling points. Are the kinetic energies the same or different?
Explain.
