it makes water distort and change. it can either make wood expand or shrink
If it won't sink in normal water, then not in salted water either
First drain the water then use the Brazilian nut effect and see if that works.
Objects from wood, cork for example.
Depends on whether salt is soluble in the glue or not. Salt would be soluble in Ordinary white wood glue, for instance. But not in epoxy glue. In epoxy, it'd simply turn the glue gritty. In wood glue it'd dissolve.
This is a factor of many things, for example, the weight of the iron and the wood, the dimensions of the container and how much water there is, but generally the water will rise because if the item is on top of the water displaces its weight in water.
Physical. Chemical change is when the composition of a molecule is changed. Example: When you burn wood. The wood stops being wood and turns to ash. An example of a Physical change is when you mix salt in water. Neither the salt nor the water change their chemical makeup. If you allow the water to evaporate the salt remains and still has the same chemical make up, as does the water even though it is now in its gaseous form.
The weight of water displaced by the floating block of wood is exactly equal to the weight of the ENTIRE block of wood, regardless of how much of the wood is above the water level.
Boyle's Law - upthrust equals the weight of fluid displaced, so the more dense fluid (salt water) will cause the wood to float higher than the less dense fluid (pure water).

It doesn't effect the wood, It CURES the WOOD!
Yes it is a good idea. so that when they get bored they dont start chewing on your wood, they just lick the salt block.
No. It doesn't matter how heavy a block of wood is, it depends on the density of the wood. Generally wood floats as the density of wood is lighter than the density of the water, so it would float.
.83 g/ml
because the wood absorbs the water and its size increases the water enters the wood through small pores
Depends on what the block is made of. A block of wood will float. A block of concrete will sink.
Wood will. A solid block of aluminum will sink. Things float when their density is less than water. There are some woods that sink.
-- The aggregate density of the wood block is 700/1000 = 0.7 the density of water. -- So, as soon as the wood has displaced 0.7 of its volume in water, it has displaced its entire weight in water, and floats. -- The wood floats with 0.7 of its volume below the surface and 0.3 of its volume above it.
