Question

What is the Celsius temperature equivalent to 400K?

Options

Choose one · Correct answer highlighted

Explanation

Relation: TC = T−273.15. Given: T = 400K. TC = 400−273.15 = 126.85∘C≈127∘C. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 127°C. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
