As a storm front moves in you notice that the column of mercury in a barometer rises to only mm. (a) what is the air pressure? kpa (b) if the mercury in this barometer is replaced with water, to what height does the column of water rise? assume the same air pressure found in part (a).

We can't answer either of these questions without knowing the number that's supposed to appear in the blank space between "only" and "mm".

The only thing I can tell you is that the missing, mystery number, when multiplied by 13.6 , will give you the answer to ' b '.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
