Yes everything that dies and it's organic matter becomes methane. Anaerobically.
Yes. All dead animals and plants do give off methane gas caused by the bacteria that are the decomposers.
Swallowing air or gas or byproducts rotting
methane
No. Uranus contains methane in its atmosphere, but it does not give off methane.
The main greenhouse gas that comes from rotting garbage is methane (about 87% by volume). But, after time, methane gas is oxidized to form carbon dioxide and water. Methane gas is a major contributer to to global warming and the Kyoto protocol seeks to regulate its production. Check out this website for more information: http://en.wikipedia.org/wiki/Methane
yes, rotting of fruit peelings produces methane (CH4) which from this source would be called biogas (and when from fossil reserves is called natural gas)
There is no 'solvent' in pure natural gas. Pure natural gas is methane (colorless and odorless). The natural gas used in stoves has methylmercaptan mixed with the methane to give the gas an odor to help detect leaks. In this case the methane is the solvent and methylmecaptan is the solute.
No, Planet Saturn cannot sustain human life. IF we made up a story, the characters would have to be "Methane Gas People" that breathe, eat, and live in methane gas. Of course, there are no real "Methane Gas People"-- I just made up that name.
Methane and carbon dioxide.
No. Methane is a combustible natural gas. Methane can be produced by rotting waste products, Sometimes, animal waste (manure) is used on farms to produce methane which is then used for heating and to make electricity. You may be confusing the name with methamphetamine, often called "Meth" which is a very addictive illegal drug.
Methane gas is a greenhouse gas used in most industries. It is an alkane (compound with CO2 and hydrogen particles).
There is evidence that substantial amounts of methane are produced from vegetation rotting under the water behind the dam.
The gas is methane (CH4).
