Why do solids have strong intermolecular forces?
Why do solids have strong intermolecular forces?
- Due to weak bonds between particles
- Because the particles are tightly packed together (correct)
- Because the particles are far apart
- Due to the high kinetic energy of particles
Why do liquids have intermediate boiling and melting points?
Why do liquids have intermediate boiling and melting points?
- Due to the close proximity of particles (correct)
- Due to weak intermolecular forces
- Because they have very high kinetic energy
- Because the particles are freely moving
Why do gases have much lower boiling and melting points compared to solids and liquids?
