Define charcoal and write its main characteristics.
Charcoal is a black, porous solid material that is primarily composed of carbon. It is produced by heating organic matter, such as wood, peat, coconut shells, or other biomass, in the absence of oxygen, a process known as pyrolysis. Charcoal has been used as a fuel source for thousands of years due to its unique properties. Here are the main characteristics of charcoal:
-
High Carbon Content: Charcoal is predominantly composed of carbon, typically containing around 80-98% carbon. This high carbon content makes it an efficient fuel source with a high energy content.
-
Porous Structure: Charcoal has a highly porous structure with many small pores and crevices. This porous nature provides a large surface area, which enhances its adsorption and absorption capabilities. ________ ________ _____ ___ _________ ______ ____ ______ ________ ______ _________ __________.
