Sublimation et solubilité du iode

Principle

Iodine, whose melting point is at 113.5 °C, evaporates clearly below this temperature. It passes from the solid state directly to the gaseous state. This process is known as sublimation.

When iodine vapour cools down, solid crystals form, again without a liquid transitional ...

Dipole properties

Principle

Molecules with dipole properties have great importance, molecules with dipole have a higher boiling point than molecules without dipole (with comparable mass). Furthermore, compounds align with dipole in an electric field.  This experiment studies the behaviour ...
