Methane is an important greenhouse gas, responsible for around 30% of the rise in global temperatures since the industrial revolution. [58] Methane has a global warming potential (GWP) of 29.8 ± 11 compared to CO 2 (potential of 1) over a 100-year period, and 82.5 ± 25.8 over a 20-year period. [59]

Table data obtained from CRC Handbook of Chemistry and Physics 44th ed. Annotation "(s)" indicates equilibrium temperature of vapor over solid. Otherwise temperature is equilibrium of vapor over liquid.
The following list has substances known to be gases, but with an unknown boiling point. Fluoroamine; Trifluoromethyl trifluoroethyl trioxide CF 3 OOOCF 2 CF 3 boils between 10 and 20° [142] Bis-trifluoromethyl carbonate boils between −10 and +10° [37] possibly +12, freezing −60° [143]
Methane clathrate (CH 4 ·5.75H 2 O) or (4CH 4 ·23H 2 O), also called methane hydrate, hydromethane, methane ice, fire ice, natural gas hydrate, or gas hydrate, is a solid clathrate compound (more specifically, a clathrate hydrate) in which a large amount of methane is trapped within a crystal structure of water, forming a solid similar to ice.
Methane traps about 28 times the heat per molecule as carbon dioxide but lasts a decade or so in the atmosphere instead of centuries or thousands of years like carbon dioxide, according to the U.S ...
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
