Coexistence of Solid and Liquid Matter: Conditions for Existing One Phase?

Click For Summary
SUMMARY

The discussion centers on the coexistence of solid and liquid phases, questioning whether a material can exist solely in one phase under all conditions of temperature and pressure. Participants conclude that it is impossible for any material to maintain a single state indefinitely, as molecular motion leads to phase transitions. The conversation also touches on extreme cases, such as neutrinos and dark matter, which challenge traditional classification schemes of matter.

PREREQUISITES
  • Understanding of phase transitions in materials science
  • Knowledge of thermodynamics, particularly temperature and pressure effects
  • Familiarity with molecular motion and kinetic theory
  • Basic concepts of particle physics, including neutrinos and dark matter
NEXT STEPS
  • Research the principles of phase transitions in materials science
  • Study thermodynamic laws and their applications to phase stability
  • Explore kinetic theory and its implications for molecular behavior
  • Investigate the properties of neutrinos and dark matter in particle physics
USEFUL FOR

This discussion is beneficial for materials scientists, physicists, and students studying thermodynamics and phase behavior in various states of matter.

I think in solid or liquid phase, there are many molecule having a very large speed due to random character in moving.So the liquid or solid matter must co-exist with other phase because some molecules escape from surface of solid or liquid matter.Then is there any condition for existing only one phase of solid or liquid?

Perhaps it's just me but I find your question somewhat incoherent. Are you asking if there is a material that always, under all conditions of temperature and pressure, exists in only one state? If so, then no, I don't think that could be possible.

One might consider that a cloud of neutrinos is always a gas.

But when you start looking for extreme cases like this, the classification scheme that you are trying to use tends to lose meaning.

Dark matter as well.

Also a good point.
 
I have a single atom. What state is it in?
