is the difference between a solid and liquid causes a solid to becom liquid and causes a liquid to become 9 as

The difference between a solid and a liquid lies in the arrangement and behavior of their particles (atoms or molecules). This difference affects how they respond to temperature changes, leading to phase transitions like melting (solid to liquid) and freezing (liquid to solid).* **Solids:** Particles are tightly packed in a fixed arrangement, often a crystal lattice. They have strong intermolecular forces holding them together, allowing them to maintain a definite shape and volume. They can vibrate in place, but don't move freely.* **Liquids:** Particles are still close together but can move around and slide past each other. The intermolecular forces are weaker than in solids, allowing liquids to flow and take the shape of their container. They have a definite volume but not a definite shape.**Melting (Solid to Liquid):**Adding heat (increasing temperature) to a solid causes its particles to gain kinetic energy. They vibrate more vigorously. When the temperature reaches the melting point, the vibrations become strong enough to overcome the intermolecular forces holding the particles in their fixed positions. The particles break free from the rigid structure and start moving around, transitioning the substance from a solid to a liquid.**Freezing (Liquid to Solid):**Removing heat (decreasing temperature) from a liquid causes its particles to lose kinetic energy. They move more slowly. When the temperature reaches the freezing point (which is the same as the melting point), the particles slow down enough for the intermolecular forces to become dominant. The particles are attracted to each other and begin to arrange themselves in a more ordered structure, forming a solid.
