Burning one cubic foot of natural gas will produce approximately how many BTUs?

The combustion of one cubic foot of natural gas typically produces about 1,000 BTUs (British Thermal Units). The correct range commonly accepted for the heat energy produced from burning natural gas aligns with the given option of 900-1,100 BTUs. This range reflects the average energy content of natural gas, factoring in the variations in gas composition and other conditions that can slightly affect the burn efficiency.

Understanding this heating value is crucial for HVAC professionals when designing systems for heating spaces, as it allows them to make informed decisions about fuel needs, equipment sizing, and energy efficiency. Proper calculations based on the BTU output of natural gas help ensure that systems operate effectively and efficiently, thereby impacting both the comfort level in buildings and the overall energy costs.

In summary, the approximate energy yield from burning one cubic foot of natural gas aligns closely with the values indicated in that range, supporting the selection of that answer as the most accurate option.
