Butane is a flammable gas that is commonly used as fuel for lighters, torches, and camping stoves. It is a colorless and odorless gas at room temperature and is a highly compressed liquid when stored in canisters or cylinders.

Butane is a hydrocarbon gas, meaning that it is composed of hydrogen and carbon atoms. It is produced from natural gas or petroleum through a refining process that separates the butane from other gases and impurities.

Butane is famous as a fuel source because it is relatively cheap, easy to transport, and has a high energy density, meaning it can store a lot of energy in a small volume. However, it can be dangerous if not handled properly, as it is highly flammable and can ignite easily.

When using butane, it's important to follow safety guidelines, such as keeping the fuel away from flames or other heat sources, using it only in well-ventilated areas, and not using it near children or pets. Additionally, it's important to use butane only with devices that are designed for use with butane, as using it with incompatible devices can be hazardous.
