Consider gases confined by a liquid, as shown below. Density of the liquid = d.gmL^(-1) h_1 and h_3in mm and p_1 , p_2 and p_3 in mm Hg. In terms of barometric pressure (P_(atm))is

Answer»

<P>`p_(ATM) + 0.1 h_1d`
`p_(atm) - 0.1 h_1d`
`p_(atm) + h_1d`
`p_(atm) - h_1d`

Solution :`P_1 > P_("atm") , P_("atm") + (h_1 DG)_(CGS) = P_1`
`P_1= P_("atm") + h_1 xx d/1000 xx 100 = P_("atm") + 0.1 h_1d` .
