A solid, such as sand, does not expand as well as a liquid, such as water, because the particles in a solid are closely packed together and have a fixed position, which restricts their ability to move and expand. In contrast, the particles in a liquid are more loosely packed and have more freedom to move and flow, allowing the liquid to expand more easily.
