It depends on the physical properties of the substance. Sometimes heating a hydrophobic substance can increase solubility. Also, heating may cause the substance to denature and dissolve. In the case of proteins, proteins can contain many hydrophobic parts but still be soluble in water. However, hydrophobic substances do not typically dissolve in water, due to the polar nature of water. Typically, scientists use the word "hydrophobic" only to describe substances that have a negligible solubility in water. You may have meant to ask "why do hydrophilic substances dissolve in water".
All substances that are water repelling are considered hydrophobic substances. Ex: Oil, Waxes, etc..
Hydrophobic Repelling, resists being combined with, or unable to dissolve in water. your wording is strange since a hydrophobic molecule repels water and not the other way around, water does not repel a hydrophobic molecule.
No. Hydrophobic literally means "afraid of water," so they will repel each other, most likely because the other substance is non-polar.
insoluble
Oil is one of the best examples of substance that is hydrophobic which canÕt mix or dissolve with water. It is highly hydrophobic because the interaction in oil is more compact than other compounds.
Some hydrophobic substances are soluble in water (ex.: proteins).
Generally hydrophobic substances are not dissolved in water at room temperature.
Water does not dissolve everything. Some substances dont mix with water. Those are hydrophobic substances, ex: oil molecules
Water does not dissolve everything. Some substances dont mix with water. Those are hydrophobic substances, ex: oil molecules
Hydro means water, phobic means to hate and philic means to love, so hydrophobic are those substances which do not dissolve in water and hydrophilic are those which easily become dissolve in water.
hydrophobic
A hydrophilic substance will dissolve in water. A hydroPHOBIC substance will not.
Hydrophilic means that a substance has an affinity for/attraction to water. It binds with water easily. [It is the opposite of hydrophobic, where a substance has an aversion for water. It forms droplets in water (like oil).]
Oil and water do not mix because the triglyceride bonds have a hydrophobic (meaning does not like water) ends and therefore it will not react (or mix) with water. Water and oil don't mix because water is a polar substance and oil is nonpolar. Polar substances will only dissolve other polar substances or ionic substances, but will not dissolve nonpolar substances. Remember "Like dissolves like."

Do you know the phrase " Like dissolves like "? it means that polar substances dissolve other polar substances, and non-polar substances dissolve non-polar substances. Oil is non-polar, while water is a polar substance. To help oil and water mix, molecules of a detergent have two halves- the hydrophilic half and the hydrophobic half. The hydrophilic part of the molecule is polar, which dissolves water molecules. The hydrophobic part is non-polar, so it dissolves the oil molecules. So, basically, detergent can dissolve both oil and water, mixing them effectively.
