B Heat Correct Answer Incorrect Answer
C Light Correct Answer Incorrect Answer
D Distance Correct Answer Incorrect Answer

Solution

Therm is a non-SI unit of heat energy equal to 100,000 British thermal units (BTU). It is approximately the energy equivalent of burning 100 cubic feet (often referred to as 1 CCF) of natural gas. Since (Natural Gas) meters measure volume and not energy content, a therm factor is used by (Natural) gas companies to convert the volume of gas used to its heat equivalent, and thus calculate the actual energy use.
