Gas particles move quickly, rapidly bouncing off each other. unlike liquid particles that roll over each other, or particles in solids, which constantly vibrate on the spot.
The individual atoms or molecules of a gas or vapour are much further apart than they are in a liquid, while atoms or molecules of solids are so close together that they cannot change places, but they can vibrate in their limited space.
Its the vibration of such particles that transfers energy within the substance.
If a gas becomes hotter its particles vibrate faster, causing expansion, which then creates rising currents called convection currents. Or, if not allowed to expand (as in a pressure vessel) the pressure will increase due to the more rapid and more frequent impacts of the particles against the walls of the vessel.
Convection currents also occur in liquids, but cannot occur in solids.
When a blacksmith heats his half-made horseshoe it is because when it is hotter the particles are further apart and it is then easier to shape the metal.
Gas molecules move randomly, and Gases have high kinetic energy.
Unless the particles collide
"Temperature is a measure of the average energy of motion, of particles in matter. When particles of matter, whether in solids, liquids, gases, or elementary plasma's, move faster or have greater mass, they carry more kinetic energy, and the material appears warmer than a material with slower or less massive particles."Simply put, temperature is the measure of the average speed of particles in motion in a gas.

Heat is a measure of the amount of energy due to the motion of the particles in a gas, liquid, or solid. Temperature is a measure of the average amount of heat energy in a given body.
Unless the particles collide
Particles of a gas are in a disorderly motion (Brownian).
The particles in a solid are closely locked in position and can only vibrate.
The random motion of particles in a gas is associated with kinetic energy. This energy corresponds to the particles' motion and is dependent on their velocity and mass.
are small, point-like particles that are in constant random motion, and have perfectly elastic collisions with each other and the container walls. Additionally, they have negligible volume compared to the volume of the container in which they are enclosed.
The substance's state (solid / liquid / gas), density, temperature, etc, is determined by motion and spacing of particles.
The motion of gas particles is related to pressure by the frequency and force of their collisions with the walls of the container. When gas particles move faster and collide more frequently, they exert a higher pressure on the container walls. On the other hand, slower particle motion results in lower pressure.
When a gas sample is heated, the particles move faster and collide more frequently with each other and the walls of the container. This increased movement and collisions lead to an increase in the pressure and volume of the gas.
Gas particles move independently because they have high kinetic energy that allows them to move freely and collide with one another. The movement of one gas particle is not influenced by neighboring particles because gases are in constant random motion due to collisions with other particles and the walls of their container. This randomness leads to a lack of long-range order in the motion of gas particles.
The source of motion in the particles that Brown investigated was due to thermal energy from surrounding molecules in the fluid (liquid or gas). This random motion, known as Brownian motion, causes the particles to move erratically and unpredictably.
Particles of gas affect each other's motion through collisions. When gas particles collide, they can transfer energy and momentum to each other, causing changes in speed and direction. These collisions influence the overall behavior of the gas, such as its pressure, temperature, and volume.
I would describe it as this: All of the particles are tightly packed together with almost no spaces between them. Their motion is very limited, unlike that of a gas where the particles are spaced further apart and they are free to move around more.
