Why Do Solids Sublime into Gas?

[THANApHD]

Any one knows the reason for the Sublimation( solid to gas). I think the attraction between the air molecules and the weaker molecular stuctured solid molecules. its and adhesion effect. the molecules in surface of the solid is being attracted by the air molecules ( such like polar molecules NO2 H2O ). but this attraction is grater than the atrraction between the other molecules in the solid. so it is separated and goes away. this is a continues action. Is this answer is right?

Your answer is wrong. If you Google on the word sublimation, you will find lots of explanations and examples.

This is a phase diagram. If you look at the graph you can see that at a low enough pressure and the right temperature, sublimation can occur. In the winter you could hang your clothes out to dry since the water would sublime off.
