Which postulate of the kinetic-molecular theory applies to the particles of a liquid? . a)they do not move freely but vibrate in a stationary position.. b)they can be compressed, which causes a large change in volume.. c)they have so much kinetic energy that their intermolecular forces are negligible.. d)they have enough kinetic energy to easily slide by each other.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
