Question
Which temperature scale uses 32∘ and 212∘ as the freezing and boiling points of water at standard pressure?
Explanation
The Fahrenheit scale defines the freezing point of water as 32∘F and boiling point as 212∘F at standard pressure (Section 10.3). 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.
