Question

give the characters of the methane gas

Answer 1

Autoignition temperature: 537 °C (999 °F; 810 K)

Chemical formula: CH4

Point group: Td

Boiling point: −161.49 °C; −258.68 °F; 111.66 K

Answer 2

Explanation:

Methane is lighter than air, having a specific gravity of 0.554. It is only slightly soluble in water. It burns readily in air, forming carbon dioxide and water vapour; the flame is pale, slightly luminous, and very hot. The boiling point of methane is −162 °C (−259.6 °F) and the melting point is −182.5 °C (−296.5 °F).
