The opposite of deposition, for 10 points, name this process that occurs in solid iodine and dry ice, the direct transformation of a solid to a gas.
A group at Penn State recently created sheets of graphene from silicon carbide using this process. The primary drying phase of lyophilization occurs via this process since the pressure of the sample is lowered, and in most laboratory syntheses of ferrocene, the final product is purified using this process. Napthalene undergoes this process at room temperature, and in most laboratory apparatuses for performing this technique, it occurs on the surface of a cold finger. This process occurs at pressures and temperatures less than the triple point, and the enthalpy of this process is the sum of the enthalpies of fusion and vaporization.
