What is the ignition temperature of methane?

The ignition temperature of methane is generally accepted to be around 595 ºC. This is the temperature at which methane will ignite in the presence of an ignition source, allowing for combustion to occur. Ignition temperature is critical for understanding fire safety, as it helps in assessing the risk of fire in environments where methane is present.

Methane, a flammable gas, requires a certain amount of thermal energy to overcome its ignition point. This understanding is crucial in applications such as gas pipelines, storage facilities, and in environments where methane might accumulate, as knowing the ignition temperature helps set safety protocols and handling procedures.

Other listed temperatures are either too low or too high, indicating they may not represent methane's ignition characteristics accurately. For instance, a temperature of 400 ºC or below may not provide enough energy to initiate combustion, while an ignition point above 595 ºC does not align with the established data for methane. Understanding these temperatures is vital for safe handling and usage of methane in practical scenarios.
