Consider gases confined by a liquid, as shown below. Density of the liquid = d."gmL"^(-1) h_(1)and h_(3)in mm and p_(1), p_(2)and p_(3)in mm Hg. Select correct relation for pressure p_(3)

Answer»

<P>`p_3 = p_("ATM") + 0.1 h_3d`
`p_3 = p_("atm") - 0.1 h_3 d`
`p_3 = p_("atm") - h_3 d`
`p_3 = p_("atm") + h_3d`

Solution :`P_3 < P_("atm")`
`(h_3 dg)_(CGS) + P_3 = P_("atm") IMPLIES P_3 = P_("atm") - 0.1 h_3d`.
