it has about 1031 btu in one cubic meter!!!!
There are 1000 liters in one cubic meter. 22.4 liters of any gas is equal to 1 mole, according to molar volume. Molar mass tells us that the main component of natural gas, met…hane, or CH4, has a molar mass of 12+1+1+1+1, or 16g per mol. 16g/mol * 1000L/m3 / 22.4 L/mol = 714g/m3 = 0.714kg/m3 Therefore, there are 0.714 kilograms in a cubic meter of natural gas. You must remember that this only applies under certain conditions. The 22.4 L/mol number is a result of the Ideal Gas Law PV=nRT. In order to equate volume with moles, P and T must be specified (R is a constant). Only at atmospheric pressure (1atm) and standard temperature (0 Celsius) is there 22.4 liters in a mole of gas.
100 cubic feet equals 1 therm
BTU should be a measure of heating content, so it will vary with composition. However, in the US, 1 cubic ft of natural gas = 1,028 BTU. 1 therm = 100,000 BTU …100 cf = 0.1 Mcf approximately 1 therm (th). or more exactly 0.0972 Mcf = 1 th. See natural gas under wikipedia.
1 Therm is 100,000 BTU, and as there are 1000 BTU in 1 cubic foot of gas, 1 Therm = 100 cubic feet. Density of methane = 0.72 kg/cubic meter which is 35.3 cubic feet, so… 100 cubic feet = 2.04 kg
I'm looking for the same answer. Up to now my guess is that as 1 m3 of natural gas weighs 0.714 Kg, the weight wont change when compressed?
1 Therm = 100,000BTU

Burning 5000 cubic meters of natural gas delivers about 180 GJ of energy in the form of heat. So, 10 million cubic meters gives 2000 times more energy or 360 TJ (360,000,000,0…00,000 Joule).
Under intense heat and pressure, the soft coal turns into hard coal.

The "therm" is a unit of energy often used in connection with various methods of home heating ... gas, oil, electric, etc. 1 therm = 100,000 BTU = 1.055 x 10 8 joules … That's the easy part. The next question is: How much energy do you get by burning a cubic meter of natural gas ? The references we found on line listed the following answers (in mega-joules): 37, 40, 37, 19 to 56, 37 to 41, 39, 38. Instead of agonizing over which one is correct, let's say there's a grain of truth in all of them, and take an average ... 38.21 megajoules per cubic meter. OK. Now we're ready to do the conversion for you: ( 1 therm / 1.055 x 10 8 joule ) x ( 38.21 x 10 6 Joule / cubic meter ) = 0.362 therm / cubic meter 2.761 cubic meter / therm . Your answer is: Multiply therms by 2.761 to find out how many cubic meters of gas you need to burn in order to produce that much heat.

The calorific value of natural gas is approximately 11 kj permetre 3 . The exact value will depend of the compoundspresent in it.
The volume of gas in a cubic meter is one cubic meter. But perhaps that is not the real question?
