No. Cork floats because it is not only lighter than water, it doesn't absorb water. That's why cork is used to seal wine and champagne bottles.
Yes, a cork does float. Cork is lightweight and has a porous structure which allows it to float on water. This property makes cork ideal for use in products such as fishing floats and buoyant materials.
Cork is so porous, I don't think you can get the glue out. It will at least stain the cork. Can you replace the damaged tile?
The speed of sound through cork is approximately 800 to 1,200 meters per second, depending on factors such as temperature and the density of the cork. This speed is relatively slower compared to sound traveling through materials like metals or water, due to cork's porous and lightweight structure. Sound propagation in cork is influenced by its unique cellular composition, which affects how vibrations move through the material.
Porous means, containing pores ie, small or tiny hole, while non-porous means, without pores or holes.
Sedimentary rocks such as sandstone are examples of porous materials.
Porous simply mean a material has pores and allows fluid to pass. There are many thousands of such materials.

No, an umbrella is not an example of a porous material. Porous materials have small holes or spaces that allow liquids or gases to pass through. Umbrellas are typically made of non-porous materials like polyester or nylon that are designed to repel water.
Yes, cork does expand when wet due to its porous nature. When cork absorbs water, it swells and becomes softer, which can affect its properties such as density and flexibility. This expansion can impact the effectiveness of cork in sealing applications, as well as its ability to provide insulation and cushioning.
porous
epoxy resin is the best for bonding different types of materials, especially non-porous materials
Ants generally do not eat cork, as cork is made from the bark of the cork oak tree and is not a food source for them. However, they may be found in or around cork materials if they are attracted to other substances, such as food residues or organic matter nearby. Some species of ants are known to chew through various materials to create nests, but cork itself is not a part of their diet.
