Answer:
Hydrogen Bonds
Step-by-step explanation:
Hydrogen bond are a type chemical bond in which a hydrogen atom that has a covalent link with one of the electronegative atoms (F, N, O) forms an electrostatic link with another electronegative atom in the same or another molecule.
Hydrogen is a colorless, odorless, flammable gas that combines chemically oxygen to form water: the light of the known elements. Symbol: H; atomic weight: 1.00797; atomic number: 1; density: 0.0899 g/l at 0°C and 760 mm pressure.
The forces that exist between molecules in a material are called intermolecular forces. Higher forces and greater difficulty in separating them result from tighter molecules.
Because of this, the forces between solids and liquids are stronger than those between gases, which leads us to the conclusion that the intermolecular force is caused by hydrogen bonds.
