Water, H2O, and methane, CH4, are both covalent molecules. A covalent molecule is a chemical compound that contains covalent bonds. A covalent bond is a bond that arises through the sharing of electrons between two atomic nuclei. In reality the bond is an electrostatic attraction between the protons of one atom and electron(s) of an adjacent atom.

Burning one molecule of methane in the presence of oxygen releases one molecule of CO2[carbon dioxide) and two molecules of H2O (water): CH4 + 2O2 ---> CO2 + 2H2O The strength of the carbon hydrogen covalent bond in the methane molecule is among the strongest in all hydrocarbons, and thus its use as a chemical feedstock is limited.

Methane is a gas, and so its molecules are already separate - the water doesn't need to pull them apart from one another. The problem is the hydrogen bonds between the water molecules. If methane were to dissolve, it would have to force its way between water molecules and so break hydrogen bonds. That costs a reasonable amount of energy.

Methane (CH4) has a lower boiling point than water. Water has a higher molecular weight than methane. The intra- molecular force in water molecule is much stronger compared top the intra- molecular force between a carbon and a hydrogen in methane. Click to see full answer. Similarly, you may ask, why does h2o have a higher boiling point than ch4?
Methane is a one-carbon compound in which the carbon is attached by single bonds to four hydrogen atoms. It is a colourless, odourless, non-toxic but flammable gas (b.p. -161℃). It has a role as a fossil fuel, a member of greenhouse gas and a bacterial metabolite.
However, methane that is released into the atmosphere before it is burned is harmful to the environment. Because it is able to trap heat in the atmosphere, methane contributes to climate change. Although methane’s lifespan in the atmosphere is relatively short compared to those of other greenhouse gases, it is more efficient at trapping heat than are those other gases.

Staying hydrated and keeping water flowing through your system aids in digestion and can prevent and reduce gas in the digestive tract.
Methane is nontoxic on its own but can become lethal when it combines with another gas. Methane causes asphyxiation by displacing oxygen. It may produce symptoms of dizziness and headache , but these often go unnoticed until the brain signals the body to gasp for air. This happens too late, and the individual collapses.

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.
High levels of methane can reduce the amount of oxygen breathed from the air. This can result in mood changes, slurred speech, vision problems, memory loss, nausea, vomiting, facial flushing and headache. In severe cases, there may be changes in breathing and heart rate, balance problems, numbness, and unconsciousness.
Water in the gas tank may lead to the car bucking, stalling or not starting at all, or starting the car could be difficult. This is because the water and fuel separate, especially when the car has been sitting for a while, and the water sinks to the bottom with the fuel on top.
