PHYSICAL PROPERTIES OF METHANE :--


FormulaCH4
Molecular Weight (lb/mol)16.04
Critical Temp. (°F)-116.2
Critical Pressure (psia)673.0
Boiling Point (°F)-258.7
Melting Point (°F)-296.5
Psat @ 70°F (psia)(note 1)
Liquid Density @ 70°F (lb/ft3)(note 1)
Gas Density @ 70°F 1 atm (lb/ft3)0.0416
Specific Volume @ 70°F 1 atm (ft3/lb)24.06
Specific Gravity0.565
Specific Heat @ 70°F (Btu/lbmol-°F)8.53

Notes: 
1 = Signifies at 70°F, the compound is above its critical temperature.
2 = Signifies that at 70°F, the compound is below the normal boiling point and only the equilibrium vapor is present at 1 atmosphere
