The major difference between solid and non-solid is the arrangement of particles. In a solid, particles are closely packed together and have a fixed shape and volume. In contrast, non-solid materials have particles that are more spread out and can move around, allowing them to take the shape of their container and have a variable volume. This fundamental difference in particle arrangement leads to distinct physical properties and behaviors between solid and non-solid materials. **

The main difference between solid and non-solid substances lies in their molecular arrangement. In solids, molecules are tightly packed together in a fixed structure, giving them a definite shape and volume. On the other hand, non-solid substances have molecules that are more loosely arranged, allowing them to flow and take the shape of their container. This difference in molecular arrangement is what distinguishes solids, like ice or metal, from non-solids, such as liquids or gases. **
