How many BTU's does natural gas contain?

1. 800 BTU's

2. 900 BTU's

3. 960 BTU's

4. 1000 BTU's

The correct answer is: 960 BTU's

Natural gas typically contains about 1,000 BTUs per cubic foot when measured at standard conditions, which is why the choice indicating 960 BTUs is often recognized as a standard approximation for calculations in the field. This value represents a close estimate of the energy content that can be harnessed when burning natural gas. It's important to understand that while the exact BTU content can vary depending on the specific composition of the natural gas, 960 BTUs per cubic foot serves as a practical figure for many applications, including boiler operation and energy assessments. This figure helps engineers and operators accurately calculate fuel needs, efficiency rates, and operational costs. The other options suggest lower levels of energy content, which do not accurately reflect the common energy value of natural gas in practical applications, leading to less reliable outcomes in operational settings.
