Solids, liquids, and gases are three states of matter. The main difference between them lies in the arrangement and movement of their particles.
In a solid, the particles are tightly packed and held together by strong intermolecular forces. These forces restrict the movement of the particles to vibrating about fixed positions. As a result, solids have a definite shape and volume because their particles maintain a fixed arrangement relative to each other.
In contrast, liquids have particles that are less tightly packed compared to solids. The intermolecular forces in liquids are weaker, allowing the particles to move more freely. While the particles in a liquid are still attracted to each other, they have enough energy to move around and slide past one another. This allows liquids to take the shape of their container. However, they still have a definite volume because the particles are still close together.
Gases have particles that are widely spaced apart and have weak intermolecular forces. The particles in a gas have high kinetic energy and are in constant, random motion. They move independently of each other and fill the entire space available to them. Gases do not have a fixed shape or volume and will expand to fill any container they are placed in.
In summary, solids have a fixed shape because their particles are tightly packed and have restricted movement. Liquids take the shape of their container because their particles can move and slide past each other. Gases have neither a fixed shape nor volume as their particles are widely spaced and move freely.
Solids are those substances that have strong intermolecular forces of attraction. Due to the strong intermolecular force of attraction, the constituent particles are located close to each other and did not move easily. Therefore, the solids have fix shape.
But in the case of liquids and gases, intermolecular forces of attraction are very weak as compared to solids. So, the constituent particles of gas and liquid are located far enough and can move easily. Therefore, the gases and liquids do not have fix shape.
