the two particles found in mater is gas and air.
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.
When air particles are further apart, you have low air density. This can result in lower air pressure.
Alpha particles are larger and heavier than beta particles, so they interact more readily with air molecules through collisions. This causes alpha particles to lose their energy more quickly and travel shorter distances in air compared to beta particles, which are smaller and lighter. Additionally, alpha particles have a higher ionization potential, leading to more interactions with air molecules and a shorter range in air.
Smoke particles move in air due to air currents, also known as convection. The warm air rises, taking the smoke particles along with it. Once the warm air cools down, the smoke particles disperse throughout the surrounding air.

Particles and Gasses
the two particles found in mater is gas and air.
air moves from particles to particles
The difference lies in the speed of particles, not in the composition or structure of the individual particles themselves. Temperature measures the average speed of particles, so the particles which compose hot air are going to be moving faster than the cold air particles. Because of this, the two take on new properties - hot air will expand more rapidly and rise, while cold air will sink.
Air particles contain oxygen.
particles of cool air are sloser together than particles of warm air

Two conditions required for cloud formation are cooling air to reach its dew point temperature and the presence of particles, such as dust, smoke, or salt, for water vapor to condense upon and form droplets.
Cloud formation requires two main conditions: saturated air, meaning the air is holding as much water vapor as it can at a given temperature, and the presence of condensation nuclei, which are tiny particles that water vapor can condense onto to form droplets or ice crystals.
