There is no such thing as "surface area" of "solubility" since the latter refers to the maximum concentration in the solution of a solid (or liquid) in a liquid. "Surface area", as applied to such a phenomenon is meaningless. However, by *increasing* the surface area of, say, a salt, by grinding it, will increase its solubility. Maybe *that* is what the questioner meant.
An ointment is any topical (on the skin) application that contains medication. A gel is anything that has a jelly-like consistency. So an ointment can be in gel form, but it can also be a cream or a liquid.
Mercury is the liquid with the strongest surface tension.

it acts along the surface of liquid
At the surface of the liquid the phenomenon is called evaporation. In the entire voume of the liquid the phenomenon is called vaporization.
