If I dissolved naphthalene in water and heated it for the purpose of separation, can it still be called sublimation?

    If you dissolved naphthalene in water you could be in for the Nobel chemistry prize. Check your mail.

      what are you talking about?? see the solubility of naphthalene in H2O here

    Naphthalene melts around 80oC, so it will be a liquid floating on the water. Hence, it will evaporate.

    Naphthalene .....

    What makes you think you can dissolve naphthalene in water?

    At 25C the solubility is 31 mg / L.... or .... 0.031g per 1000g of water

    That's not very soluble.

    Naphthalene does undergo sublimation, but very slowly. The water will have evaporated before there is a noticeable change in the naphthalene. Its usefulness as "mothballs" would be limited if it disappeared quickly.

    names of phase changes

    .. solid --> liquid.. . ..melting

    .. solid --> vapor.. . ..sublimation

    .. liquid --> solid.. . ..freezing

    .. liquid --> vapor.. . .vaporization

    .. vapor --> liquid.. . .condensation

    . .vapor --> solid.. . ..deposition

    dissolution is NOT a phase change regardless of why you do it.
