a partial vacuum
Particles of carbon that enter the air when wood or coal are burned are called soot or particulate matter. These particles can contribute to air pollution and have negative health effects when inhaled.
air has mass
Alpha particles can be stopped by a few centimeters of air. At normal atmospheric pressure, about 3-4 inches of air is sufficient to absorb alpha particles and reduce their energy to a harmless level.
This happens when the air cools. If the water particles get close enough to form liquid, the process is called condensation.
Alpha particles are positively charged particles consisting of two protons and two neutrons. They have low penetration ability and can be stopped by a piece of paper, clothing, or a few centimeters of air. However, they can be harmful if inhaled or ingested.

Regions of air that have few particles are known as low-air-density areas. These regions can be found at high altitudes in the atmosphere, such as the stratosphere or thermosphere, where air particles are more widely spaced apart due to lower pressure. These areas are also associated with cleaner air quality and less pollution due to fewer particles being present.

Particles of carbon that enter the air when wood or coal are burned are called soot or particulate matter. These particles can contribute to air pollution and have negative health effects when inhaled.
The friction between a moving object and air particles is called air resistance or drag. It is a force that opposes the motion of the object and can affect its speed and trajectory.
Particles of carbon that enter the air when wood and coal are burned are called soot or particulate matter. These tiny particles can contribute to air pollution and have harmful effects on human health and the environment.
A region of air with relatively few particles is known as a low-pressure system or a partial vacuum. These regions can occur naturally, such as at high altitudes in the atmosphere, or they can be created artificially, such as in a vacuum chamber.
The range of beta particles in the air is up to several hundred feet. Beta particles are emitted by specific types of radioactive nuclei. Potassium-40 is a type of radioactive nuclei that emits beta particles.
Alpha particles have a range of a few centimeters in air and are stopped by a sheet of paper or human skin. Their penetration range in tissue is limited to a few cells.

Many materials are packed full of easily-movable charged particles. Any material that does not contain easily-movable charged particles is called an "insulator". Charged particles do not flow through an insulator. Common insulators are rubber, plastic, nylon and air. (Rubber, plastic, and nylon are packed full of charged particles, but those particles are "bound" into a solid, unmoving configuration. The particles in air are easily-movable, but they are practically all uncharged particles -- and also there are so few of them that air is mostly empty space compared to solids).
