How many BTUs are required to raise 10 lb of water by 1 degree Fahrenheit?

To determine how many BTUs are required to raise the temperature of 10 pounds of water by 1 degree Fahrenheit, it is essential to understand the specific heat capacity of water. The specific heat capacity of water is roughly 1 BTU per pound per degree Fahrenheit. This means that to raise 1 pound of water by 1 degree Fahrenheit, 1 BTU is needed.

In this case, since we have 10 pounds of water and we want to raise its temperature by 1 degree Fahrenheit, we multiply the amount of water (10 pounds) by the amount of energy needed to raise 1 pound of water by 1 degree Fahrenheit (1 BTU). Therefore, the calculation is as follows:

10 pounds × 1 BTU/pound/degree Fahrenheit = 10 BTUs.

Thus, to raise 10 pounds of water by 1 degree Fahrenheit, 10 BTUs are required. This makes the answer 10 BTUs the correct choice, as it accurately reflects the energy needed based on the specific heat of water and the given weight.
