Answer:
Osmotic pressure is a measure of a solution's tendency to attract or take in water from another solution when the two solutions are separated by a semipermeable membrane
The order of increasing osmotic pressure is
- 0.7% KCl
- 1.5% KCl
- 1.8% KCl
- 5.0% KCl
- 8.6% KCl
Explanation:
Osmotic pressure is the strength of movement of the solvent of a solution through a semipermeable membrane separating solutions of different concentration thereby causing the solvent (such as water) to move from a region of high solute concentration to a region of lower solute concentration.
The amount of osmotic pressure through a semipermeable membrane separating solutions of different concentration is given by
π = i×M×R×T
π = osmotic pressure
i = van't Hoff's factor
(M) = molar concentration
(T) = temperature in kelvin
R = ideal gas constant (0.08206 L atm mol⁻¹K⁻¹)
As seen above , the osmotic pressure is directly proportional to the concentration of the solution thus in the order of increasing osmotic pressure we have
- 0.7% KCl
- 1.5% KCl
- 1.8% KCl
- 5.0% KCl
- 8.6% KCl
Answer:Surface currents are caused by differences in water density; deepwater currents are caused by wind.

Answer:
space between particles
Explanation:
Properties of gases:
Molecule of gases randomly move everywhere and occupy all available space.
Gases don't have definite volume and shape and take the shape and volume of container in which it present.
Their densities are very low as compared to the liquid and solids.
Gas molecules are at long distance from each other therefore by applying pressure gases can be compressed.
The very weak inter molecular forces are present between gas molecules.
Properties of Liquid:
Liquid have definite volume but don,t have definite shape.
Their densities are high as compared to the gases but low as compared to the solids.
In liquid, molecules are close to each other and have greater inter molecular forces as compared to the gas molecules.
Properties of solids:
Solids have definite volume and shape.
In solids molecules are tightly pack and very close to each other.
Their melting and boiling point are every high.
The densities of solids are also very high as compared to the liquid and gas.
There are very strong inter molecular forces are present between solid molecules.
