What is particule?
Particulates are tiny subdivisions of solid matter suspended in a gas or liquid. Sources of particulate matter can be man made or natural like Air pollution and water pollution can take the form of solid particulate matter. Particulates is a complex mixture of extremely small particles and liquid droplets.
What is the name for solid particles around which clouds can form?
The name for the solid particles around that the clouds can form is called atmospheric particulate matter. Another name for atmospheric particulate matter is particulates.
Particulate matter is nade of tiny bits of dust smoke salt and similar particles Why is particulate matter important for clouds to form?
It serves as condensation nuclei, or surfaces for water vapor to condense on
What does a snowflake represent?
Ice crystals from condensed water vapor that form on particulate matter in the atmosphere
What is briquettes?
A process and system is provided for briquetting particulate matter such as moisture-containing bituminous and sub-bituminous coal. This process includes partially drying the particulate matter and feeding, the partially dried particulate matter to a briquetting apparatus (38) under conditions such that water vapour is released from the particulate matter during feeding. The particulate matter is passed through briquette forming rollers (44, 46) to form briquettes (47). The released water vapour substantially displaces or prevents the ingress of a large proportion of other gaseous components from the atmosphere surrounding an/or intermixed with the particulate matter. The particulate matter that is fed to the briquetting apparatus is surrounded by and intermixed with a gaseous component containing 70 to 100 % by volume of water vapour at the point where it enters the briquette-forming part of the briquetting apparatus, such that when the particulate matter is compressed during briquette formation, the water vapour liquefies and the pressure buildup of gaseous material in the thus-formed briquettes is minimised. This reduction in the pressure buildup of gaseous components also acts to reduce blow-back of gases as the coal fines are being formed into briquettes. http://www.wipo.int/pctdb/en/wo.jsp?wo=2004072212
What is an example of particulate matter?
Material suspended in the air in the form of minute solid particles or liquid droplets, especially when considered as an atmospheric pollutant.

What is a change in which one or more types of matter form?
"chemical"
What threatens air quality?
Air quality can be threatened by pollutants from sources such as vehicle emissions, industrial activities, wildfires, and agricultural practices. These pollutants can include particulate matter, nitrogen oxides, sulfur dioxide, volatile organic compounds, and heavy metals, which can have harmful effects on human health and the environment.
Matter contains different types of metal?
Some types of matter contain one or more metals either in elemental form or as ions but not all.
What is a change in which one or more new types of matter form?
"chemical"
Is coal pollution?
Coal in itself is not a form of pollution, it is a substance formed from dead and fossilised plant matter. However it creates polluting substances, namely the gas carbon dioxide, when burnt.
