Definitions:

Hydrogen Bonds

These are weak bonds formed between a hydrogen atom in one molecule and an electronegative atom (usually oxygen or nitrogen) in another molecule.

Cohesion

The force that holds molecules of the same substance together, important for phenomena such as surface tension and the movement of water through plant vessels.

Osmotic Pressure

The force exerted by a solution to move water across a semipermeable membrane, aiming to equalize solute concentrations on both sides.

Ionic Bonds

Chemical bonds formed between two ions with opposite charges, typically between a metal and a non-metal, where one atom transfers electrons to another.
