What is the value of absolute zero?

• A. 0 °C
• B. 273.15 K
• C. -273.15 °C
• D. -100 °C

Answer: (C)

Verified step by step guidance

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