On a planet if there is no atmosphere can we find water on it? Water vapour on it?
Evaluate the following statements.
Statement I: Ice can persist in cold traps and transient water vapour can occur; stable exposed liquid is not possible below the triple-point pressure.
Statement II: No atmosphere means water molecules cannot exist in any form.
Options:
Answer:
B
Solution:
Stable exposed liquid water is not possible at a pressure below the triple-point pressure. Ice may persist in cold traps and may sublime into transient vapour. The outcome depends on temperature, illumination, gravity and the duration considered; no atmosphere does not imply no ice or transient vapour. Statement I is true and Statement II false. Correct option: (B).
