Question
Which of the following is true about the Celsius and Fahrenheit scales at the ice point?
Explanation
At the ice point (freezing of water at standard pressure), Celsius is 0∘C and Fahrenheit is 32∘F (Section 10.3). As per NCERT, applying relevant law/formula with correct units and sign convention leads to Celsius is 0∘, Fahrenheit is 32∘. This satisfies dimensional consistency and physical conditions given, so option D is scientifically correct.
