Which of the following corresponds to a temperature of zero on the Kelvin scale?

• A. Freezing point of water
• B. Boiling point of water
• C. Room temperature
• D. Absolute zero

Answer: (D)

Verified step by step guidance

1. Understand the Kelvin temperature scale: it starts at absolute zero, which is the lowest possible temperature where particles have minimal thermal motion.
2. Recall that the freezing point of water corresponds to 273.15 K on the Kelvin scale, not zero.
3. Recognize that the boiling point of water is at 373.15 K on the Kelvin scale, which is much higher than zero.
4. Note that room temperature is typically around 298 K, again well above zero Kelvin.
5. Conclude that zero on the Kelvin scale corresponds to absolute zero, the theoretical temperature where molecular motion ceases.
