yes they are related
Melting, freezing, vaporizing
This depends on your definition of vaporizing and what is done after vaporizing it. Assuming this is a illicit drug use related question, then yes, breathing cough syrup vapours could kill you or at least damage your lungs. Cough syrup is intended to be ingested, not inhaled.
There are many synonyms for evaporation. Some of these are: melting, vaporizing, disappearing, lessening, dispelling and desiccation.
Uranium is a solid at normal temperatures, melting at 1132° C and vaporizing above 3818° C.
Vaporizing doesn't kill cold sores.
Yes, vaporizing requires an input of energy to heat the substance to its vaporization point. This energy causes the substance to change from a solid or liquid state to a vapor or gas state.
Examples of sublimation include dry ice (solid carbon dioxide) turning into carbon dioxide gas without melting, mothballs slowly disappearing without leaving a residue, and snow vaporizing into water vapor without melting into liquid water.
Freezing and melting are related. Freezing is going from a liquid to a solid, and melting is going from a solid to a liquid. The energy used for this phase change is called heat of fusion. Condensing and vaporizing are also related in a similar way. Condensing is going from a gas to a liquid and vaporization is going from a liquid to a gas. The energy used for this phase change is called heat of vaporization. Evaporation and boiling are similar. Both refer to the change of a liquid to a gas, but evaporation takes place on the surface of the liquid, and boiling takes place on the entire mass of the liquid.

Thermally unstable compounds are decomposed before melting or boiling.
