Consider the following two situations, in which case will the volume occupied by the sponge be greater?
Situation 1: Sponge on a table
Situation 2: Sponge soaked in water
Situation 1
Sponge is porous. It have holes in it which is filled with air. When the holes are filled with water it shrinks as water occupies lesser space than air as it has stronger molecular forces of attraction.
