Methaan is a colorless, odorless gas that is the simplest form of hydrocarbon. It is composed of one carbon atom and four hydrogen atoms, giving it the chemical formula CH4. Methane is a primary component of natural gas and is commonly used as a fuel for heating, cooking, and electricity generation. In addition to its use as an energy source, methane is also produced by natural processes, such as the decomposition of organic matter in landfills and the digestive processes of ruminant animals like cows. However, methane is a potent greenhouse gas, contributing to climate change when released into the atmosphere.
