What are the physical properties of methane ?

The physical properties of methane are :-

(i) Methane is a colorless, odorless, and tasteless nonpoisonous gas.

(ii) Methane is sparingly soluble in water but dissolves readily in alcohol and ether.

(iii) Methane is lighter than air.

(iv) Methane melts at -184°C and boils atomic -161.4°C.

(v) Methane like carbon dioxide, also traps infrared radiations (heat radiations) reflected by the earth. As a result, methane gas also contributes to the greenhouse effect. Actually, a molecule of methane traps twenty times more heat radiations than a carbon dioxide molecule.
