A material that despises or "fears" water is referred to be hydrophobic or hydrophobic (the fear of water). Such materials include all oils and fats, which are immiscible with water.
Hydrophobicity is the property of some molecules and compounds to repel water. Other substances attract water because they have hydrophilic surfaces. The word "hydrophile" is an adjective meaning "repelled by water"; thus, a hydrophilic substance is one that attracts water.
Some organic chemicals are hydrophobic. These include many fats and oils, which tend to dissolve in non-aqueous solvents rather than water. Inorganic chemicals are also hydrophobic, such as carbon disulfide and benzene. These substances are not soluble in water, but they do not resist it either. They feel oily when touched by water.
Many drugs are hydrophobic. This is because most drugs contain carbon rings or carbons attached to other atoms, which makes them come together out of shape so they can fit into protein receptors in our bodies. This brings us back to why drugs are called medications - they treat diseases by putting things back into balance where they don't belong.
Water phobia (two definitions): an irrational dread of water. Acrophobia: a deep-seated fear of heights. Hydrophobia: a form of rabies that causes severe pain when the victim swallows his or her tongue.
The term "hydrophobia" was first used by the Greek physician Aulus Celsus in his book De Medicina (50 AD). He described it as a disease caused by a poison produced by insects that had been washed into jars of wine. The symptoms include pain when swallowing, paralysis of the muscles of the throat, and eventually death due to asphyxiation.
Hydrophobia can be cured with time and treatment, but there is no cure for the disease itself. Although extremely rare, people who develop hydrophobia do not recover consciousness and therefore do not recover either. Instead, they spend their last days in excruciating pain before dying from asphyxiation.
People often fear what they don't know. This theme is reflected in the names of two other medical conditions also derived from Greek words for water: aquaphobia and amphiphobia. Aquaphobia refers to the fear of water, while amphiphobia means the fear of both water and land.
The term "hydrophobicity" is derived from two Greek words: "hydro," which means "water," and "phobos," which means "fear." As a result, hydrophobic substances are those that commonly display the attribute of hydrophobicity. The opposite is true for hydrophilic substances.
Base word play is when the meaning or spelling of one word in a phrase or sentence can be changed by adding or removing letters. In this case, the change affects what kind of feeling is suggested by the word. For example, if you write "give me a hard time," the implied feeling is difficult; but if you replace the word "hard" with the word "soft," the meaning changes completely and becomes possible to give someone a soft time.
In chemistry, a hydrophobe is a chemical compound or molecular structure that is generally considered to be water-repellent. The term was first used by organic chemists who were studying how plants protect themselves from being soaked in water. They found that certain chemicals on the surface of plants prevent water from bonding to the plant's cells. This way, even if water does contact the cell, it cannot stay long enough to do any damage.
Hydrophobes often make up the protective layer of a plant's skin or leaves. They help plants resist moisture and soil contamination. Water and soil pollution can come from inside the plant as well as outside.
To be hydrophobic implies to be afraid of water. In chemistry, it refers to a substance's ability to resist water. A hydrophobic material has hydrophobicity and is so called hydrophobic. Instead of being exposed to water, hydrophobic molecules are nonpolar molecules that combine together to form micelles. Micelles are small spheres formed by the joint action of surfactants or detergents and water.
Hydrophilic substances attract water. They are polar molecules that can be dissolved in water. Hydrophilic compounds have hydroxyl (OH) groups which attach to water molecules. The more OH groups there are on a molecule, the more easily it will dissolve in water. Commonly occurring hydrophilic substances include sugars, acids, and alcohols.
Some materials are moderately hydrophilic or hydrophobic. For example, cellulose, the main component of paper, is a polysaccharide made up of glucose units linked together. Each glucose unit has an oxygen atom attached to it with a negative charge. This makes the whole polymer somewhat hydrophilic. However, since the oxygen atoms are attached to carbon atoms that are also bonded to other molecules, the cellulose fiber does not experience much attraction to water on its own. It requires several fibers to create a network that is sufficiently strong to use for papermaking.
Lignin is another example of a hydrophilic material that becomes hydrophobic when combined with other molecules.
Aquaphobia is a distinct phobia. This is an unjustified dread of something that does not provide a significant risk. If you notice that any source of water gives you undue worry, you may have aquaphobia. A swimming pool, a lake, the ocean, or even a bathtub can be considered. The fear must be quite serious to be classified as a phobia.
People with aquaphobia cannot overcome their fear and will avoid anything that could be considered water even if it isn't directly connected to water. They will also avoid places where water might be found such as lakes, ponds, and rivers.
The fear must be quite severe for it to be classified as a phobia. If someone is only afraid of deep water or water that is moving quickly they would not be diagnosed with a true phobia of the ocean or bathing pools. Someone who is afraid of all animals including snakes and spiders would not be diagnosed with a true phobia of insects because the fear is not very intense. However, if someone was also afraid of scorpions then they would be diagnosed with a true phobia of insects because this fear is very strong.
Someone who is only afraid of dogs but not cats or other animals would not be diagnosed with a true phobia of animals because the fear is not very intense. However, if someone was also afraid of cockroaches then they would be diagnosed with a true phobia of insects because this fear is very strong.
