Which scale measures temperature relative to the freezing and boiling points of water with 180 intervals between them?
The Fahrenheit scale uses 32∘F for freezing and 212∘F for boiling of water, with 180 intervals (212−32 = 180) between these points. As per NCERT, applying relevant law/formula with correct units and sign convention leads to Fahrenheit. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
