be much “harder” at high altitude since the external pressure is lower at high
altitude.
A “high altitude” ball will be “soft” at sea level.
5.Explain why the height of mercury is independent of the diameter of the mercury column.
6.How high in meters must a column of water be to exert a pressure equal to that of a 760 mm column of mercury?
