    Methane can also be found in coal gas. Pockets of methane exist naturally underground. In homes, methane may be used to fuel a water heater, stove, and clothes dryer. Methane evaporates quickly. Therefore, most of the methane that ends up in lakes, streams, or soil is eventually released into the air.

  • Why is methane (CH4) a gas and methanol (CH3OH) a liquid ...

    Why is methane (CH4) a gas and methanol (CH3OH) a liquid? In chemistry we are learning about polar bonding and hydrogen bonding, so I know the answer is related to this, but I don't understand how.

    Jan 15, 2009 · The "lifetime" of methane—defined as the time it takes for the gas concentration to drop by a factor of the mathematical constant e, or roughly three—is 300 to 600 years, depending on the ...

  • Are there CO2 emissions from natural gas? | HowStuffWorks

    The burning of fossil fuels -- like coal, oil and natural gas -- releases gases into the air, mainly carbon dioxide, sulfur dioxide, methane and nitrous oxide. These also exist naturally in the Earth's atmosphere to help hold in heat; however, scientists believe burning fossil fuels is causing an increase in these gases, which is leading to ...

    Methane is an odorless, colorless gas, or a colorless, odorless liquid in its cryogenic form. Both the liquid and the gas pose a serious fire hazard when accidentally released. The liquid will rapidly boil to the gas at standard temperatures and pressures. As a gas, it will act as a simple asphyxiant and present a
