You smell things because particles of the item are floating in the air and registering in your nose. If you heat something up it makes substances more volatile. This just means that since the thing is hotter its particles have more energy, and so can escape from the object into the air more easily.

The Short Answer

You smell things because particles of the item are floating in the air and registering in your nose. If you heat something up it makes substances more volatile. This just means that since the thing is hotter its particles have more energy, and so can escape from the object into the air more easily. Also bacteria and fungi grow more readily in warmer temperatures, and so there is simply more smell due to that.
