Question

multiple-choice question absolute zero (0k) is equal to -273.15°c 0°c

Explanation:

Absolute zero in the Kelvin scale (0 K) is a fundamental concept in thermodynamics (a subfield of Physics, which is part of Natural Science). The conversion between Kelvin and Celsius is given by the formula \( T(^\circ\text{C}) = T(\text{K}) - 273.15 \). When \( T(\text{K}) = 0 \), substituting into the formula gives \( T(^\circ\text{C}) = 0 - 273.15=- 273.15^\circ\text{C} \). \( 0^\circ\text{C} \) is the freezing point of water, not absolute zero.

Answer:

• \( -273.15^\circ\text{C} \) (the option with this value is the correct one), \( 0^\circ\text{C} \) is incorrect.
