<human>: What's the difference between natural gas and liquefied natural gas?
<bot>: Natural Gas is a fossil fuel that is found in underground reservoirs. It is composed of methane, which is a chemical compound made up of carbon and hydrogen atoms. Liquefied Natural Gas (LNG) is a form of natural gas that has been cooled to liquid form so it can be more easily transported and stored. LNG is typically stored in tanks at -260 degrees Fahrenheit (-162 Celsius).
