Inertia
Because hot gas particles have greater kinetic energy than cold gas particles
It means that a gas condenses, it becomes a liquid again. It typically does this as it cools down. The condensation forms on surfaces or particles. Rain is condensation that has formed around dust particles.
A gas cannot easily pass through a liquid or a solid however it can be entrapped in it . If a gas bubble is formed in a liquid it moves upward and escapes out of the liquid. Gas cannot pass through a solid barrier.
No. Gas particles move much faster than solid particles.
When a gas is heated, the kinetic energy of the gas particles increases. This causes the particles to move faster and farther apart, leading to an increase in pressure and volume. Heating a gas also increases the average speed of the gas particles.
No. Volcanic ash is not gas. It is made of tiny solid particles of rock or glass formed either when molten rock is fragmented or when solid rock is pulverized by explosive eruptions. Gas from a volcano is simply called volcanic gas.
Gas particles are typically smaller than smoke particles. Gas molecules are individual atoms or small clusters of atoms that are very spread out and move freely. Smoke particles, on the other hand, are larger aggregates of solid or liquid particles that are suspended in the air.
The particles of gas have more energy and are less tightly packed than particles in solids. This allows gas particles to move freely and change position easily, while solid particles are held in a fixed position by strong intermolecular forces.
Solid particles in gas are called aerosols. These are tiny solid or liquid particles suspended in a gas, such as dust, smoke, or mist.
Unless the particles collide
