The “bends” is a medical condition that results from N2 dissolving in the blood when
diving deep underwater and then escaping
and forming bubbles in the blood when the
diver rises to the surface where the pressure is
less. This is best described as an example of
1. Raoult’s Law.
2. Hess’ Law.
3. saturation vapor pressure.
4. minimum boiling azeotrope.
5. Henry’s Law.

Explanation:

"Bends" is caused because the pressure deep underwater is considerably larger thant the atmospheric pressure.

As Henry's Law states, the solubility of a gas in a liquid is proportional to the partial pressure of the gas over the solution: the larger the pressure of the gas, the larger the solubility.

That means that deep underwater, where the pressure is high, more nitrogen gas will be dissolved in the blood of a diver than what can be dissolved on the surface, where the pressure is less.

The nitrogen gas that cannot be dissolved in the blood at lower pressures, when the diver rises to the surface, will form bubbles in the blood that will reach the tissues where they will cause health problems.

Thus, this is an example of Henry's Law: statement 5 from the choices.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
