1030-1060 BTU/cf 1 gal (US) = 0.133 cf (cubic foot) 1 cf = 7.48 gal converting units, 138 - 142 BTU/gal X 600 ( the approximate volume change from liquid to gas = 84,000 BTU/galhttp://www.retailenergy.com/hybrid/Liquified%20Natural%20Gas.htm The previous answer neglected to account for the difference in the BTU/vol of methane as a liquid vs the BTU/vol of methane as a gas
One gallon of liquefied natural gas (LNG) is equivalent to about 0.136 cubic feet.
Many powders and solids can be melted (liquefied) by heat. For instance, sugar and butter is often melted in cooking.
The energy content of a gallon of salt water would depend on the concentration of salt in the water. On average, seawater contains about 3.5% salt. Using this concentration, a gallon of salt water would contain very minimal energy in the form of trace amounts of potential thermal energy due to the dissolved salt. It would not be practical to extract energy from a gallon of salt water in this context.
1 CCF of natural gas is roughly equal to 1 gallon of propane.
It would seem that for many people, the fact that an energy source is "natural" is not the only criterion to select an energy source.
One gallon of liquefied natural gas (LNG) is equivalent to about 0.136 cubic feet.
Generally, one gallon of LNG (liquefied natural gas) contains around 135,000 British Thermal Units (BTUs) of energy. This high energy content makes LNG an efficient fuel source for various applications in transportation and industry.
There are approximately 46 megajoules of energy in 1 kilogram of LPG (liquefied petroleum gas).
97 cubic feet of natural gas will make 1 liquid gallon.
One gallon of kerosene will produce 134,000 BTUs of energy when burned.
Many powders and solids can be melted (liquefied) by heat. For instance, sugar and butter is often melted in cooking.
There are approximately 3.9 mmBTU in 1 kg of LNG (liquefied natural gas). This value can vary slightly depending on the specific composition of the LNG.
The energy content in fuels is often measured in BTU (British Thermal Units). I'm assuming that you're talking about compressed natural gas, as in the form that is used in some cars like the Honda Civic GX. One gallon of compressed natural gas contains 138,700 BTU. One gallon of gasoline contains 125,000 BTU. [http://www.bts.gov/publications/national_transportation_statistics/2002/html/table_04_06.html]
60% * 500 = 300three hundred gallons (of liquid - the gas before being liquefied - takes up MUCH more volume)
The energy content of a gallon of salt water would depend on the concentration of salt in the water. On average, seawater contains about 3.5% salt. Using this concentration, a gallon of salt water would contain very minimal energy in the form of trace amounts of potential thermal energy due to the dissolved salt. It would not be practical to extract energy from a gallon of salt water in this context.
One gallon of liquid petroleum gas (LPG) contains approximately 91,500 BTUs (British Thermal Units) of energy.
