Solids can't be compressed. The sponge is not solid because it can be compressed.
False
Solids have a definite shape and definite volume. A piece of sponge can retain its shape and size when no external force is acting. The sponge has minute pores with some amount of air trapped in it. Upon pressing the sponge, the air is expelled out and it gets compressed. Thus, the sponge is a porous solid and given statement is false.
