Intermolecular forces are the attractive forces between molecules. In solids, molecules are tightly packed with minimal space between them, resulting in maximum intermolecular forces. This gives solids a definite shape and volume. In gases, molecules are far apart with maximum space, leading to minimum intermolecular forces, allowing gases to expand freely. Both statements about solids having maximum forces and minimum spaces, and gases having minimum forces, are correct.

Final Answer: All of the above
