What state of matter has the strongest intermolecular forces?
Ksivusya [100]

Answer:

Solid

Explanation:

As the temperature continues to drop, the matter forms a solid. Due to the solid's low kinetic energy, particles have no "time" to move around, the particles have more "time" to be attracted. Therefore, solids have the strongest intramolecular forces (because they have the strongest attraction).
