However, as soon we heat the wood, for instance with a match or a lighter, we see that the wood catches fire.

This is an example of a chemical reaction, where cellulose molecules in the wood and actually being converted into among other things, carbon dioxide, the stuff of dry ice and what we breathe out.

Examples of solids that sublime are dry ice solid carbon dioxide , iodine, arsenic, and naphthalene the stuff mothballs are made of.

This is a great question that is more difficult to answer than you would suspect. If you are interested in learning more, please free to ask. Any solid may be sublimed if its temperature and pressure are below its triple point. For example, if you were to freeze water into ice and cool it further and then reduce the pressure, you could get ice to sublime.

Some other examples include: Dry ice solid CO2 which sublimes at atmospheric pressure and C, and C60 buckyballs which sublimes at atmospheric pressure at around K. Some common solids go through sublimation at standard pressure 1 atmosphere. Carbon dioxide sublimates at Iodine is another substance that has been observed to sublimate at room temperature and pressure.

The phase relationships of a chemical are expressed on a phase diagram with pressure and temperature as the two axes. A number of solids are capable of sublimating at normal temperatures and pressures, including snow, iodine, arsenic, and solid carbon dioxide dry ice.

Sometimes other materials can be made to sublimate by creating low pressure conditions. If you take a materials science class in the future probably in college , then you will learn to read "phase diagrams," which are basically graphs that show what temperatures and pressures are required to have solid, liquid or gas phases for a material.

One interesting element that sublimates is Arsenic. Because Arsenic does not melt at a normal pressure it sublimates instead. One interesting fact is that if one puts an Arsenic crystal in a test tube, they can see the gas which Arsenic sublimated into. Lastly I want to point out that Arsenic can condense under special circumstances.
