When a substance is heated, the molecules within it gain kinetic energy and begin to move more rapidly. In a solid, the molecules are tightly packed together and have limited freedom of movement. As the solid is heated, the molecules vibrate more vigorously within their fixed positions, causing the solid to expand slightly.
In a liquid, the molecules are already in a more disordered state and have more freedom of movement compared to a solid. When the liquid is heated, the molecules move even more rapidly and with greater freedom, causing the liquid to expand more significantly than a solid.
Overall, the increased kinetic energy and movement of molecules in a liquid allow for greater expansion compared to a solid when both are heated.

In a solid, the molecules are tightly packed together in a regular arrangement, forming a rigid structure. When heat is applied, the molecules gain energy and vibrate more vigorously, but they remain in their fixed positions. This causes the solid to expand slightly.
In a liquid, the molecules are also closely spaced, but they are not arranged in a regular pattern. When heat is applied, the molecules gain energy and move more freely. This allows them to move further apart from each other, causing the liquid to expand more than a solid.
The difference in expansion between liquids and solids is due to the different ways in which the molecules are arranged. In a solid, the molecules are held in place by strong intermolecular forces, which prevent them from moving freely. In a liquid, the intermolecular forces are weaker, allowing the molecules to move more easily.
The expansion of liquids and solids is an important consideration in many engineering and industrial applications. For example, the expansion of metals is used to create thermostats, which control the temperature of a system by expanding or contracting a metal coil. The expansion of liquids is used to create thermometers, which measure temperature by measuring the change in volume of a liquid.
