How many BTUs are released approximately when burning one cubic foot of natural gas?

  1. 800 BTUs

  2. 1,050 BTUs

  3. 12,000 BTUs

  4. 15,000 BTUs

The correct answer is: 1,050 BTUs

Burning one cubic foot of natural gas typically releases approximately 1,050 BTUs. This value is based on the standard heating value of natural gas, which varies slightly depending on its composition but generally falls within this range. Understanding this value is essential for calculations related to heating efficiency, sizing of equipment, and estimating energy costs for residential or commercial heating systems. Recognizing the heating value helps technicians and engineers make informed decisions when designing systems for optimal performance. The other choices represent approximate values for different energy sources or quantities of natural gas and may not accurately reflect the heat energy available from one cubic foot of natural gas specifically.
