Crystals, Polymorphs, solvates

Hygroscopic(ity)=Readily absorbing moisture, as from the atmosphere

Amorphous=solid-like liquid

Instant coffee is amorphous, whereas Filter coffee is crystalline.

Modification of Crystal Habit= A change in external shape without changing molecular order

Modification of Crystal Form= A change in internal molecular order

Hailstone=ουσ. μετεωρ. κόκκος χαλαζιού

compaction=ουσ. (απαρχ.) συμπίεση, σύμπτυξη: compaction of particles συμπίεση μορίων # γεωλ. συμπαγής υφή ή κατάσταση

Rhomboderal=diamond -like crystals

Thermodynamically driven to revert to the crystalline form. instead of change back

sublimation=ουσ. εξιδανίκευση, εξευγενισμός # εξαΰλωση # χημ. εξάχνωμα ή εξάχνωση

refraction index=

ουσ. οπτ. διάθλαση: angle of refraction γωνία διάθλασης

A measure of the extent to which a substance slows down light waves passing through it. The index of refraction of a substance is equal to the ratio of the velocity of light in a vacuum to its speed in that substance. Its value determines the extent to which light is refracted when entering or leaving the substance.

rectangle=ουσ. ορθογώνιο παραλληλόγραμμο

rectangled=επίθ. ορθογώνιος
