First The meaning of sublimation is a chemical process where the solid change into a gas without going through the liquid stage.

The conditions necessary to occur are:

1- Need the pressure to be lower than the triple point.

2-The temperature must be high enough to produce a gas.

3-The substance must be in its solid state.

 sublimation occurs because the atoms in a solid must gain enough energy to form a gas without passing through the liquid state. Low air pressure and large amounts of energy, often in the form of heat, allow the atoms to move fast enough to overcome the attractive forces between them.
