Which option best describes a unit of energy?

• A. Energy
• B. Temperature
• C. Therm
• D. Pressure

Answer: (C)

A unit of energy is a standard amount used to quantify energy itself. The therm fits this role because it’s a defined energy quantity used in gas and heating contexts: 100,000 BTU, which is roughly 29.3 kilowatt-hours. So the therm is the best description among the options as a specific unit used to express energy. Energy and the therm are different ideas: energy is the concept of capacity to do work, while a unit like the therm is the standard measure for expressing how much energy is present. Temperature describes how hot or cold something is, not how much energy it contains, and pressure is the force per area that a substance exerts, not a measure of energy.
