Intermolecular force of attraction
pinterest.com
- Particles of matter are attracted to one another by force known as the intermolecular force of attraction. The intermolecular force of attraction varies between the three states of matter. It is greatest in solids, which is why they are strong and do not change their structure. It is very low in gases due to which it can be compressed.

The particle theory of matter or the kinetic molecular theory of matter describes the microscopic properties of atoms (or molecules) and their interactions, which result in observable macroscopic properties (such as pressure, volume, and temperature).

Solids (like liquids) are not very compressible due to the lack of space between molecules; If the molecules in a solid adopt a highly ordered packing arrangement, the structures are said to be crystalline; Due to the strong intermolecular forces between neighboring molecules, solids are rigid.
Solids, liquids and gases. In a solid like this brick, the particles are regularly arranged touching their neighbours and move only by vibrating. This explains why solids have a fixed shape.
Apr 16, 2023 · Under appropriate conditions, the attractions between all gas molecules will cause them to form liquids or solids. This is due to intermolecular forces, not intra molecular forces. Intra molecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms.
Particles in a solid are tightly packed together (fixed shape) and often arranged in a regular pattern; in a liquid, they are close together with no regular arrangement (no fixed shape); in a gas, they are far apart with no regular arrangement (no fixed shape).
Gases. In the gas state, the particles have complete freedom of motion and are not held together. The particles are constantly flying around, bumping into each other and the container. There is a large amount of space between the particles compared to the size of the particles.
Nov 26, 2020 · In solids, intermolecular forces of attraction are strongest while thermal energy is minimum (only due to vibratory motion about the mean position of constituent particles and no translatory motion at all). In liquids, the two types of energies are intermediate between those of gases and solids. The Gaseous State.
