Glycerophospholipids have a polar head group that interacts with water molecules, making them soluble in water. Triglycerides lack this polar head group, which makes them less soluble in water.
Except at EXTREME pressures (like over 200 MPa), ice is less dense than liquid water. In the case of polar water this is even more the case since polar water has a fair amount of salt dissolved into it, raising it's density, while the ice is nearly pure water.
Water is more polar than 2-propanol because it has a greater difference in electronegativity between oxygen and hydrogen atoms, leading to a larger dipole moment. 2-propanol also has a dipole moment due to the hydroxyl group, but it is less polar than water.
Do water molecules in the liquid state have more energy than water molecules in the polar state
Sugar is more soluble in water than caffeine. Sugar molecules are polar and can form hydrogen bonds with water molecules, allowing them to dissolve easily. Caffeine is less soluble in water due to its nonpolar nature, making it less likely to interact with water molecules.

Iodine is not soluble in water because iodine is nonpolar and water is polar. According to the "Like dissolve like" expression, nonpolar substances are soluble with nonpolar substances and polar substances are soluble with polar substances, but nonpolar substances are not soluble with polar substances.
Thymol is considered to be moderately polar due to the presence of hydroxyl (OH) groups, which can participate in hydrogen bonding. It is more polar than non-polar compounds like hydrocarbons, but less polar than highly water-soluble compounds.
Covalent bonds are generally less soluble in water compared to ionic bonds. Ionic compounds dissolve in water because of the attraction between the ions and the polar water molecules. In contrast, covalent compounds are usually nonpolar or have weaker polar bonds, making them less likely to interact with polar water molecules and dissolve.
Water is more polar than alcohol is. The molecule contains two strongly polar O-H bonds and no other bonds. A molecule of alcohol contains one highly polar O-H bond, one somewhat less polar C-O bond, and a nonpolar hydrocarbon segment.
Glucose is more soluble in water than cyclohexanol because glucose is polar. In contrast, cyclohexanol is mostly nonpolar and therefore less soluble in water.
Water is more polar than ethanol. This is because water has stronger hydrogen bonding due to the presence of more hydrogen-bonding sites (two hydrogen atoms and one oxygen atom), making it a better solvent for polar substances. Ethanol is also polar but has weaker hydrogen bonding compared to water.
It's in water.
