NCERT · Class 11 · Physics · Thermal Properties of MatterWhat is the absolute zero temperature on the Celsius scale?
Step-by-Step Solution
Absolute zero ($0 \text{ K}$) corresponds to $-273.15^\circ\text{C}$ on the Celsius scale because $T(\text{K}) = t(^\circ\text{C}) + 273.15$. Hence, option A is correct.
