SUMMARY

The discussion centers on the potential for elements and compounds to exist as liquids on Venus, given its extreme atmospheric pressure and temperature conditions. It is established that any substance with a melting point below 460°C and a boiling point above 460°C could theoretically exist as a liquid on Venus. Participants agree that understanding the phase changes of various compounds is crucial for identifying those that could flow and rain on the planet's surface.

PREREQUISITES
  • Understanding of phase changes in materials
  • Knowledge of Venus's atmospheric conditions
  • Familiarity with melting and boiling points of elements and compounds
  • Basic principles of planetary science
NEXT STEPS
  • Research the melting and boiling points of compounds like sulfuric acid and phosphoric acid
  • Investigate the atmospheric composition of Venus
  • Explore the concept of supercritical fluids in planetary atmospheres
  • Study the geological features of Venus that may indicate liquid flow
USEFUL FOR

Astronomers, planetary scientists, and researchers interested in the chemical and physical properties of extraterrestrial environments, particularly those studying Venus's atmosphere and potential for liquid compounds.

I understand that, given Earth's distance from the Sun and it's atmospheric pressure, it is possible for liquid water to flow and to rain down on Earth's surface. I also understand that, given Titan's distance from the Sun and it's atmospheric pressure, it is possible for liquid methane to flow and to rain down on Titan's surface. My question is:

Given Venus's distance from the Sun and it's atmospheric pressure, which element(s)/compound(s) COULD (hypothetically) exist as a liquid and flow and rain down on Venus's surface?

You mean which compounds could exist as BOTH a liquid and a gas? Without evaporation there can be no rain.
 
Any element or compound with a melting point less than 460° C and a boiling point greater than 460° C.
 
Drakkith-
quite right

Dr_Morbius-
...and which elements/compounds might those be?
