Detailed explanation-1: -Materials with a special affinity for water-those it spreads across, maximizing contact-are known as hydrophilic. Those that naturally repel water, causing droplets to form, are known as hydrophobic.

Detailed explanation-2: -Something defined as hydrophilic is actually attracted to water, while something that is hydrophobic resists water. This means when hydrophobic items come in contact with liquids, water is encouraged to bead up and roll off the surface-almost pushing it away like a magnet pushes away metal objects.

Detailed explanation-3: -A hydrophilic molecule or substance is attracted to water. Water is a polar molecule that acts as a solvent, dissolving other polar and hydrophilic substances. In biology, many substances are hydrophilic, which allows them to be dispersed throughout a cell or organism.

Detailed explanation-4: -Substances dissolving readily in water are called hydrophilic compounds. They consist of ions or polar molecules that use electrical charge effects to attract water molecules. The water molecules surround these polar molecules and carry them into the solution, thereby dissolving them.

Detailed explanation-5: -Hydrophilic molecules are polar in nature and easily form a hydrogen bond with water thereby getting dissolved in water. Notably, these interactions between the hydrophilic molecule and water are thermodynamically favored.
