Final answer:
1 pound of water can be heated from 63°F to 64°F using 1 BTU.
Step-by-step explanation:
1 BTU is the amount of energy needed to heat one pound of water by one degree Fahrenheit. To find out how much water can be heated using 1.0 BTU from 63°F to 64°F, we need to calculate the energy required to heat water by one degree Fahrenheit and then divide 1.0 BTU by that value.
Based on the given information, 1 BTU is the energy required to heat one pound of water by one degree Fahrenheit. So, to heat one pound of water from 63°F to 64°F, we need 1 BTU/°F.
Therefore, 1 pound of water can be heated from 63°F to 64°F using 1 BTU.
