What are the Effects of Dust on the Lungs OSH Answers

Dusts are tiny solid particles scattered or suspended in the air. The particles are inorganic or organic, depending on the source of the dust. Inorganic dusts can come from grinding metals or minerals such as rock or soil. Examples of inorganic dusts are silica, asbestos, and coal. Organic dusts originate from plants or animals.

Factors Affecting Reaction Rates Chemistry

Factors Affecting Reaction Rates Chemistry

Hence, the rate of a reaction between two phases depends to a great extent on the surface contact between them. A finely divided solid has more surface area available for reaction than does one large piece of the same substance. Thus a liquid will react more rapidly with a finely divided solid than with a large piece of the same solid..4617 raymond mills from St.Petersburg

How does surface area affect a chemical reaction? If one of the reactants is a solid, the surface area of the solid will affect how fast the reaction goes. This is because the two types of molecule can only bump into each other at the liquid solid interface, i.e. on the surface of the solid. So the larger the surface area of the solid, the ...

How size determines rate STEM Activity

Background. A chemical reaction normally involves liquids, gases or solids. Some reactions happen very fast, whereas others seem to take ages. In heterogeneous chemical reactions, which means whenever a solid is one of the reactants, you can actually change the reaction rate by varying the size of the solid that reacts with the liquid or the gas.
