Perfumes solid state

You know matter exists as gases, liquids, and solids because you can smell the perfume of flowers, pour fruit punch into a glass, and stack blocks of firewood. You know that air, water, and rocks all feel different, but can you describe their macroscopic properties The properties that characterize these three states of matter—gas, liquid, and solid—reveal the organization of their submicroscopic particles. 

Depending on temperature and pressure, all materials in the solid and liquid state have a vapour pressure, that is, some of their surface atoms or molecules exist as a vapour or gas above the material. Thus under certain conditions a liquid evaporates and some solids sublimate. This is most familiar to us as we smell coffee or perfumes the fragrant molecules leave the liquid and enter the surrounding atmosphere. Mothballs are an example of the tendency of solids, like naphthalene, to enter the gaseous state. Volatility is the meas-...
