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 phase. This process is known as
resublimation.

Tasks
