Emissions are gases and other particles(微粒)that are released into the atmosphere as a result of burning fuels and other processes.The most common types generally come from automobiles,power plants,and industrial companies.The results of too many emissions being released into the atmosphere are ...

A gas giant may be classified as a planet whose original composition is of gases, such as hydrogen and helium, with a small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune. These planets are known asJovian Planets. They were named as such...
athey emit gases make noise .and keep crashing into each other.there are so many paths and so many metal particles that it is impossible to land a flying saucer without its being smashed by one. 他们散发气体做噪声.and保留碰撞成彼此.there是许多道路和那么许多金属微粒登陆你没有它捣毁的飞碟是...
Device for the deposition of particles that are specifically heavier from gases, mute or the like by means of centrifugal forces.DALIN DAVIS
Particles with no pattern and with complete freedom of movement are: A) solids B) liquids C) gases States of Matter: A state of matter is defined as a distinct form by which matter can exist. We differentiate between the states based on the qualitative differences...
healthily. Phytoplankton is a tiny creature that cannot be seen by the human eye. It lets out a chemical (化学物质) called dimethyl sulfide (二甲基硫) into the air. The chemical works with other gases in the atmosphere and makes tiny particles (微粒). They then come together to form ...

Living things, for example, are mostly made from the atoms carbon, hydrogen, and oxygen. These are just three of over 100 chemical elements that scientists have discovered. Other elements include metals such as copper, tin, iron and gold, and gases like hydrogen and helium. You can make ...
Particles and fibres affect human health as a function of their properties such as chemical composition, size and shape but also depending on complex interactions in an organism that occur at various levels between particle uptake and target organ responses. While particulate pollution is one of the...
