An industrial thermometer is heated until the mercury inside it is exerting 400 N of force against the inner surface. That surface has a total area of 200 cm2. How much pressure is the mercury exerting against the inner surface of the thermometer? Note that 1 Pa = 1 N/m2.

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.

What are two examples of phase changes that skip a phase during transition?
