According to the KMT, temperature is a measure of the average KE of molecules in an object. The Units of Heat: The units of heat are calories (cal), Joules (J), and British thermal units (Btu). The older unit of energy was the . calorie (cal). One calorie is the amount of heat required to raise 1 g of water by 1 Cº.

Another popular unit of heat energy is the Btu (British thermal unit). One Btu is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. Using the conversion factors of 2.2 lbs/kg and 1.8 F°/C°, and Joule's equivalent, we find that: 1 Btu = 252 cal = 1055 J.

We will assume that in your house the hot water is heated to 140 degrees F, and the water starts out at 55 degrees. To raise the temperature of one gallon of water by 85 degrees requires 440 BTU. To determine your total energy usage for hot water heating, multiply gallons used by 440. Example: I took a ten minute shower

To raise the temperature of 1 pound of water 1oF requires one BTU. If one pound of water at 62oF is raised to 212oF liquid, 150 BTU’s would be required. When one pound of water at 212oF is converted to steam, an additional 970 BTU’s are absorbed. The total number of BTU’s absorbed in converting one pound of water at 62oF to steam is 1,120 ...
