Final answer:
The correct relationship between the intermolecular forces in a solid and its melting temperature is (c) As intermolecular forces increase, the melting temperature increases.
Step-by-step explanation:
The intermolecular forces play a significant role in determining the physical properties of a substance, including its melting temperature. Intermolecular forces, such as van der Waals forces and hydrogen bonding, are responsible for holding molecules together in a solid.
When intermolecular forces increase, the attraction between molecules becomes stronger. As a result, more energy is required to overcome these forces and transition the substance from a solid to a liquid state. This increased energy requirement corresponds to a higher melting temperature. Conversely, if intermolecular forces are weak, less energy is needed for the transition, leading to a lower melting temperature.
Understanding this relationship is crucial in materials science and chemistry. Scientists and engineers can manipulate intermolecular forces to design materials with specific melting temperatures, which is essential in various industries, including the development of alloys, polymers, and other advanced materials. The relationship between intermolecular forces and melting temperature provides valuable insights into the behavior of substances under different conditions
