The prefix Therm- is associated with which concept?

• A. Cold
• B. Heat
• C. Therm-
• D. Light

Answer: (B)

The main idea here is understanding what the prefix therm- means. Therm- comes from a Greek root meaning heat, and it's used in medical terms to signal something related to heat or temperature. You can see this in words like thermometer (measures temperature), thermodynamics (the science of energy related to heat), and thermal (relating to heat). Because of that, therm- is associated with heat. The other options don’t fit because different prefixes signal different things: cold is shown by cryo- or frigor-, and light is indicated by photo- or lumino-. So therm- specifically points to heat, not cold or light.
