Answer:
Intermolecular bonds
Step-by-step explanation:
Physical separation is known to break intermolecular bonds. Intermolecular bonds are the bonds between molecules of a substance.
These attractive forces between molecules determines the intermolecular interactions.
Chemical changes takes place between the intramolecular bonds. Intramolecular bonds are found between atoms of a substance. These bonds are the ones that forms new compounds when a product results in a chemical reaction.
Physical separation deals with intermolecular forces of attraction between compounds.
