Answer:
Correct option d = Sublimation
Step-by-step explanation:
We know that gases occupy more volume as compared to the solid and liquid. Gases occupy all the available space.
In given option option D is correct because,
Sublimation is the process in which solid is directly converted into the gaseous phase without passing through liquid phase. So when substances under goes sublimation they are converted into gaseous form and occupy more space.
Oher options are incorrect because,
Deposition involve the conversion of gas into solid. Thus volume decreased. This option is incorrect.
Option B is also incorrect because,
Melting involve the conversion of solid into liquid. Volume increased as compared to solid state but not as much like in case of gases.
Option C is also incorrect because,
Vaporization involve the conversion of liquid into gaseous form. Volume also increase in this case but the volume increase in case of sublimation is higher than in case of vaporization that's why this is also incorrect.
