Answer:
one
Explanation:
In solids, molecules do not posses translatory motion. Therefore, they occupy fixed positions. As a result, they have any number of free surfaces. In gases, molecules posses translatory motion in all directions randomly. Therefore, they do not have fixed positions and do not posses translatory motion which is not random like gaseous molecules and the upper suface is free. Hence, they have only one free surface.
