    a. The act of perspiration must be chemically stimulated. The evaporation of sweat is physical.

    d. Dissociation involves breaking bonds, but it depends what is dissociating. If it's an ionic compound in solution then it is usually defined as physical, while it is actually chemical in nature, as bonds are being formed with the solvent.
