4 Οκτ 2024 · The boiling point of methane is −162 °C (−259.6 °F) and the melting point is −182.5 °C (−296.5 °F). Methane in general is very stable, but mixtures of methane and air, with the methane content between 5 and 14 percent by volume, are explosive.
The methane phase diagram shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the methane boiling point with changes in pressure.
Methane has a boiling point of −161.5 °C at a pressure of one atmosphere. [3] As a gas, it is flammable over a range of concentrations (5.4%–17%) in air at standard pressure . Solid methane exists in several modifications .
Learn why methane (CH4) has a low boiling point of -161.5 0 C or 111.65 K. Compare boiling points of methane with other compounds and answer questions on boiling point of methane.
