Water ice traps gases even after phase changes. The amount of gas released depends on ice thickness, with implications for comets.

Area of Science:

  • Planetary Science
  • Materials Science
  • Physical Chemistry

Background:

  • Amorphous ice transitions to cubic ice at specific temperatures.
  • Trapped gases within ice can be released during phase transitions or sublimation.

Purpose of the Study:

  • To investigate gas retention in water ice beyond the amorphous-to-cubic ice transformation.
  • To determine the relationship between ice thickness and gas release.
  • To explore the implications for cometary outgassing.

Main Methods:

  • Experimental simulation of ice formation and phase transitions.
  • Controlled heating and sublimation of water ice samples.
  • Measurement of released gas quantities.

Main Results:

  • Water ice retains trapped gases above the amorphous-to-cubic ice transformation temperature.
  • Gas release during cubic-to-hexagonal ice transition and sublimation is linearly dependent on ice layer thickness.
  • Experimental data provides insights into gas retention mechanisms in icy bodies.

Conclusions:

  • Water ice's capacity to retain gases is significant even after initial phase changes.
  • Ice thickness is a critical factor controlling gas release, relevant to cometary activity.
  • Findings contribute to understanding the composition and evolution of comets.
