Final Answer:
True. One of the factors determining the states of matter is the inter/intramolecular forces holding the particles together. The intermolecular forces between particles determine the physical properties of molecules like their boiling point, melting point, density, and enthalpies of fusion and vaporization
Step-by-step explanation:
The intermolecular forces holding the particles together are one of the factors determining the states of matter. These forces are attractive forces between molecules and they determine many of the physical properties of a substance. In contrast, intramolecular forces are the forces within a molecule that hold the atoms together.
For example, in water (H2O), the intramolecular forces are the covalent bonds holding the hydrogen and oxygen atoms together within each water molecule. The intermolecular forces between water molecules are hydrogen bonds, which contribute to the unique properties of water, such as its high boiling point and surface tension.
