WitrynaIntermolecular forces are the forces of attraction that pulls molecules together so that there can be properties of matter for condensed states. A condensed state is the opposite of gas state. A condensed phase is either a solid or a liquid and the molecules are all held close together by IMFs. The strength of the IMFs will determine a ...
Witryna31 maj 2024 · Like most concepts in chemistry, intermolecular forces takes a bit of imagination and critical thinking to fully comprehend and apply when explaining a variety of situations.
