    • Cohesion is the property of like molecules that stick to each other due to mutual attraction.
    • Adhesion is the property of different molecules or surfaces to cling to each other.
    • Surface tension is a contractive tendency of the surface of a liquid that allows it to resist an external force
    • Polarity the property of having poles or being polar.
    • pH The pH scale measures how acidic or basic a substance is.


More Information

A macromolecule is a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer. Some examples of macromolecules are synthetic polymers (plastic, synthetic fibers, and synthetic rubber), graphene, and carbon nanotubes. Natural molecules are for example the bio-polymers such as DNA, carbohydrates, proteins and lipids, or polyphenols.
