How many BTUs are required to heat 1 gallon of water by 1 degree Fahrenheit?

  1. 5.33

  2. 6.25

  3. 7.50

  4. 8.33

The correct answer is: 5.33

The other options, B, C, and D, are not the correct answer because they are calculated using the specific heat capacity of water, which represents the amount of energy required to heat 1 gram of water by 1 degree Celsius. However, the question is asking for the amount of energy required to heat 1 gallon of water, which is approximately 3,785 grams, by 1 degree Fahrenheit. Therefore, the correct answer is A, as it is the only option that takes into account the larger amount of water and the smaller temperature change.
