Which of the following is closest to the boiling point of neon in kelvin?

• A. 77 K
• B. 4 K
• C. 273 K
• D. 27 K

Answer: (D)

Verified step by step guidance

1. Recall that the boiling point of a substance is the temperature at which it changes from liquid to gas at atmospheric pressure.
2. Understand that neon is a noble gas with very weak intermolecular forces, so it has a very low boiling point compared to water (273 K) or nitrogen (77 K).
3. Recognize that the boiling point of neon is much lower than common liquids and closer to temperatures near absolute zero, so it should be closer to a few kelvin rather than tens or hundreds.
4. Compare the given options: 77 K (liquid nitrogen boiling point), 4 K (close to helium's boiling point), 273 K (water's boiling point), and 27 K, and identify which is most reasonable for neon based on its physical properties.
5. Conclude that the boiling point of neon is closest to 27 K, as it fits the expected range for a noble gas with weak intermolecular forces.
