salt water, as the salt water eats away at the coin faster.
I think it's because salt dissolves better in hot water than cold water, so as the solution cools the salt wants to come out of solution and crystallize. When you pour the solution over the sponge, this causes the liquid to evaporate. This further concentrates the salt so that it will crystallize. The salt crystals will start to form on undissolved salt or on the sponge. Once the crystals start forming, they grow fairly rapidly...
No. Ice is simply frozen water. It can melt but it does not decompose.
An example of an item that is soluble in water is salt. If you put salt in water, the salt disappears. An insoluble item in water is oil or sand, because no matter how many times you stir it, the sand or oil is always there.
The large opening at the top of the sponge, where water leaves, is called the osculum. It is responsible for expelling the water and waste products from the sponge's body.

Salt dries out the fish. The fish still decomposes but it's much, much slower. Water speeds up the decomposition. Since the fish is now dry because of the salt it doesn't decompose as fast.

It is impossible.
First, I choose an oil and then make a sodium soap in ethanol. Finally, I decompose it in water with an excess of a calcium salt.
When a sponge is submerged in water, the water enters the sponge through the tiny holes in the sponge. The sponge fills up with water, as a balloon fills with air, only not as visibly. When you squeeze the sponge, the water exits that sponge through the tiny holes...exactly the opposite of how it entered! Tada! :)
a sponge holds water because of its holes
A sponge is something that has allot of holes, but can still hold/soak up water.
