Here we have to get the height of the column in meter, filled with liquid benzene which exerting pressure of 0.790 atm.
The height of the column will be 0.928 m.
We know the relation between pressure and height of a liquid placed in a column is: pressure (P) = Height (h) × density of the liquid (ρ) × gravitational constant (g).
Here the pressure (P) is 0.790 atm,
or [0.790 × (1.013 × 10⁶)] dyne/cm². [As 1 atm is equivalent to 1.013 × 10⁶ dyne/cm²]
Or, 8.002ₓ10⁵ dyne/cm².
density of benzene is given 0.879 g/cm³.
And gravitational constant (g) is 980 cm/sec².
On plugging the values we get:
8.002×10⁵ = h × 0.879 × 980
Or, h = 928.931 cm
Or, h = 9.28 m (As 1 m = 100 cm)
Thus the height will be 9.28 m.
Answer:
Explanation:
Mixture: is combination of one or more substances mix together.
• The properties of the mixture are not same and contains the properties of all those component present in it.
• it is a combination of one or more Pure substances and can be separated by simple physical methods.
• it have varying boiling and melting point
Homogeneous Mixture: are those which are not distinguish by naked eye but can be separated into its components by physical means.
The components of a homogeneous mixture are in the same phase oar in dissolved form so it look like one component.
Examples are:
• Salt water is mixture of water and NaCl and can be separated by physical mean.
• Air: mixture of gases
Heterogeneous mixture: are those which can be distinguishing by naked eye and can be separated into its components by physical means.
The component of heterogeneous mixture not fully mixed are different in color or different in phases or not soluble. So one can easily see the difference in the component of the mixture
Examples is
• mixture of salt and sand
• mixture of water and sand
