A cork is less denser than water because cork is floating on water so it will have less density than water
Cork insulates, is water resistant and floats in water.
The cork will float on the surface of the water because cork is less dense than water. The cork displaces a volume of water equal to its own weight, allowing it to float. If the cork is pushed under water, it will pop back up due to its buoyant force.
because cork is less dense than water
An impervious rock is one that does not allow water to flow through it. It has no air spaces and has no way of storing water at all.
No. It may soften the cork but if anything hot water will make the cork expand.
i am not a master in biology but something i know that in plants the bark cells are impervious to gases and water as they have a chemical called suberin on their walls.
Cuticle being impervious to water prevents water loss
Cork is a light weight wood product that will float in water.
