The boiling point of methane (CH4) is approximately -161.5 degrees Celsius (-258.7 degrees Fahrenheit) at standard atmospheric pressure.
Methane is a simple hydrocarbon, consisting of one carbon atom bonded to four hydrogen atoms. Its low boiling point is due to the weak intermolecular forces present, specifically London dispersion forces, which are typical in nonpolar molecules. As the temperature increases, these forces can be overcome, allowing the methane to transition from a liquid to a gaseous state.
