Understand that absolute zero is the lowest possible temperature where particles have minimal thermal motion.
Recall the relationship between Celsius and Kelvin temperature scales: \(T_{K} = T_{\degree C} + 273.15\).
Recognize that absolute zero corresponds to 0 K on the Kelvin scale.
Use the conversion formula to find the Celsius equivalent of 0 K: \(T_{\degree C} = T_{K} - 273.15\).
Calculate \(0 - 273.15\) to find the temperature in Celsius, which defines absolute zero.
