To soften a hard sponge, you can soak it in warm water for about 10-15 minutes until it absorbs the moisture and becomes pliable. Alternatively, microwaving a damp sponge for about 1-2 minutes can help restore its softness, but be sure to let it cool before handling. If the sponge is too worn out, consider replacing it, as repeated hardening might compromise its ability to clean effectively.
A dry sponge is hard because the water has evaporated, leaving the sponge's cellular structure collapsed and less flexible. When water is added, the cells absorb water and expand, allowing the sponge to become soft and flexible.
a sponge is an invertabrate it has no back bone some sponges have holes in the body so they can breath and capture food. sponges skin is made out of soft spongey tissue.
No, it is not possible to make soft foam stiff again.
The harder silica or calcium spicules are absent and the softer spongin remains.Answer:They are soft because they should not hurt the body parts while having a bath. the skin is too soft to use a bath sponge, if the sponge is too hard.
I believe that the Coral specimen is hard and rocky, though there could also be specimens that are soft, considering that Coral comes in all shapes, sizes, and colors. It is more often hard and bumpy than soft like a sponge.

soft wood is easy to cut but not good to make stuff and hard wood is hard to cut but good to make with
hard water can be converted to soft water by boiling, filteration etc.
A sponge can be both soft when wet and rough when dry.
Soft objects have a low rigidity and can easily change shape when pressure is applied, while hard objects have high rigidity and maintain their shape under pressure. Soft objects often have a smooth surface texture, while hard objects are typically rough or firm to the touch. Examples of soft objects include pillows or sponge, while examples of hard objects include rocks or metal.
