Solids can't be compressed. The sponge is not a solid because we are able to compress it.
False
The sponge has minute pores in which air is trapped. Upon pressing the sponge, the air is expelled out and is the reason why we are able to compress it. So, we are not compressing the sponge here, but expelling the air out of the sponge. Thus, the sponge is solid with minute pores and hence, the given statement is false.
