Methane (CH4) is an odorless and colorless flammable gas and serves as a superior fuel source. It autoignites at approximately 538°C, spontaneously combusting when reaching specific temperatures.
Characterized by a blue flame, methane can reach peak temperatures around 1400°C. Upon mixing with air, it becomes explosive between 4.5% and 16% concentrations. Below this threshold, it burns actively, while above, it sustains a more subdued combustion.
