Tiny particles invisible to the human eye, such as dust, dirt, an pollutants, provide surfaces on which water molecules can condense and gather into water droplets
Small particles in the atmosphere that serve as the core of tiny condensing cloud droplets. These may be dust, salt, or other material.
tiny particles in the atmosphere which provide a surface for water molecules to condense on
A particle upon which condensation of water vapor occurs. It may be either in a solid or liquid state.
are small particles in the air that attract water and encourage condensation.
Small particles in the air around which water vapor condenses.
Particles of dust that act as a nucleus, an essential component in the crystallization of water to a solid.
Microscopic particle of dust, smoke or salt that allows for condensation of water vapor to water droplets in the atmosphere. Nucleus for the formation of a rain drop. Condensation normally occurs on these particles when relative humidity becomes 100 %. Some condensation nuclei, like salt, are hygroscopic and water can condense on them at relative humidities lower than 100 %.
