Click For Summary
Sublimation, the process of a solid transitioning directly to a gas, is influenced by the interactions between air molecules and the solid's surface molecules. The discussion suggests that the adhesion effect plays a role, where the attraction between air molecules and the weaker molecular structure of the solid is stronger than the attraction among the solid's own molecules. This leads to the solid's surface molecules being separated and released into the gas phase. However, this explanation is challenged, with a recommendation to consult additional resources for a more accurate understanding of sublimation. A phase diagram is referenced, indicating that sublimation can occur under specific temperature and pressure conditions, exemplified by the drying of clothes in winter due to sublimation of water.

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.

I came.across a headline and read some of the article, so I was curious. Scientists discover that gold is a 'reactive metal' by accidentally creating a new material in the lab https://www.earth.com/news/discovery-that-gold-is-reactive-metal-by-creating-gold-hydride-in-lab-experiment/ From SLAC - A SLAC team unexpectedly formed gold hydride in an experiment that could pave the way for studying materials under extreme conditions like those found inside certain planets and stars undergoing...
