How many gallons of mid-grade gasoline are equivalent to the energy content of 1 cord of apple wood?

The energy content of various fuels can be compared by converting their energy values into a common unit. In this case, we are comparing the energy released from burning a cord of apple wood to that released from burning mid-grade gasoline.

A cord of apple wood typically produces about 25 million BTUs (British Thermal Units) of energy when burned. Mid-grade gasoline, on the other hand, averages approximately 124,000 BTUs per gallon.

To find the equivalent amount of gasoline in gallons that matches the energy output of one cord of apple wood, you can perform the following calculation:

1. Divide the total energy output of the apple wood (25,000,000 BTUs) by the energy content of the gasoline per gallon (124,000 BTUs/gallon).

[

\text{Gallons of gasoline} = \frac{25,000,000 \text{ BTUs}}{124,000 \text{ BTUs/gallon}} \approx 201.61 \text{ gallons}

]

This calculation results in roughly 201.61 gallons, which means that the mid-grade gasoline equivalent to the energy content of 1 cord of apple wood is approximately 200 gallons when rounded to the nearest whole number
