If you put a piece of chalk in water, don't expect much to happen. The chalk, which is calcium carbonate (CaCO3), will displace some water and sink. It will grow in mass by a small amount since it is permeable and is absorbing the water.
Nothing will happen when you add water to chalk, because chalk does not dissolve in water. However, if you are drawing with chalk, as the water evaporates, it will allow the chalk to spread and create more fun.
chalk is a compound
Chalk is a sedimentary rock composed of the skeletal remains of tiny marine organisms and is composed mainly of the mineral calcite. As such, chalk is not a mineral.
