Methane

Methane is a chemical compound with the chemical formula CH₄. It is a colorless, odorless gas that is the main component of natural gas. Methane is the simplest alkane and is a major component of many organic compounds. It is also a potent greenhouse gas and plays a significant role in climate change.

Properties of Methane

• Chemical Formula: CH₄
• State: Gas at room temperature and pressure
• Odor: Odorless
• Flammability: Highly flammable
• Solubility: Insoluble in water

Uses of Methane

Methane has numerous industrial and domestic uses:

• It is a major component of natural gas used for heating and cooking.
• It is used as a fuel for vehicles and power plants.
• It is a feedstock for the production of various chemicals, including hydrogen, methanol, and acetic acid.
• It is used in the production of ammonia for fertilizers.

Environmental Impact

Methane is a potent greenhouse gas, and its release into the atmosphere contributes to global warming and climate change. Sources of methane emissions include natural processes such as wetlands and the digestive systems of ruminant animals, as well as human activities such as fossil fuel extraction, agriculture, and waste management.
