The correct answer is -273.15 °C.

Absolute zero is defined as 0 Kelvin (0 K). The relationship between the Celsius scale (°C) and the Kelvin scale (K) is given by the formula T(K) = T(°C) + 273.15.

To convert 0 Kelvin to degrees Celsius, we rearrange the formula: T(°C) = T(K) – 273.15. Substituting T(K) = 0, we get T(°C) = 0 – 273.15 = -273.15 °C. Absolute zero is the theoretical point where particles have minimum vibration and zero point energy, and it is the lowest possible temperature.
