Question

Sponge has a fixed shape and it looks solid but it can be easily compressed .Why?

Answer 1

We know that sponge has a fixed shape and looks solid.

We also know that it absords water from it's container.

This is all because sponge has many air spaces . When we press sponge the air from the air spaces escapes and the shape of the sponge changes.

Thus the sponge gets compressed when pressed . This is reason why we can easily compress sponge.
