If a liquid twice as dense as mercury were used in a barometer, approximately how high would the column of that liquid be under normal sea-level conditions?

Respuesta :

Answer:

Explanation:

Given

If the density of liquid is twice as dense as mercury then

[tex]\rho _{liquid}=2\times \rho _{mercury}[/tex]

where [tex]\rho _{mercury}=density\ of\ mercury [/tex]

[tex]\rho _{liquid}=density\ of\ liquid[/tex]

Column of liquid w.r.t sea level is mercury is used is =760 mm of Hg

as the atmospheric Pressure is same therefore

[tex]\rho _{mercury}h_{1}g=\rho _{liquid}h_2g[/tex]

[tex]h_2=\frac{\rho _{mercury}}{\rho _{liquid}}\cdot h_1[/tex]

[tex]h_2=\frac{1}{2}\times 760=380\ mm\ of\ Hg[/tex]
