$2.(15$ pts$.)$ A manometer consists of a U$-$shaped tube containing a liquid. One side is connected to the apparatus and the other is closed to the atmosphere. The pressure inside the apparatus is then determined from the difference in heights of the liquid. Suppose the liquid is mercury and the closed side is $15\mathrm{.}0$ cm higher than the side connected to the apparatus. Draw the set$-$up for this experiment. What is the pressure in the apparatus? The density of mercury at $25$C is $13\mathrm{.}55$ g$.$cm$^3,1$ atm$=101325$ Pa$,$ acceleration of free fall g$=9\mathrm{.}81$ m$.$s$-2$
