Chalk is destroyed when it comes into contact with water or moisture, which dissolves the calcium carbonate that makes up the chalk. It can also be physically broken down by scraping or erasing, which breaks the chalk into smaller pieces or powder.
When chalk is shaken, it breaks down into smaller particles, creating a fine powder. This powder is more easily dispersed and adheres better to surfaces when drawn or written with.
No, the size of the beaker does not determine how fast or slow water cools down. The rate at which water cools down is primarily influenced by the temperature difference between the water and its surroundings, the material of the beaker, and any insulation present around the beaker.
No, once chalk dust has been created from a chalk stick, it cannot be transformed back into a solid piece of chalk. The dust particles are broken down and cannot reassemble into a solid form.
When chalk is dissolved, the solid particles of chalk break down and disperse into the liquid it is dissolved in. This results in a homogeneous mixture where the chalk particles are spread out evenly throughout the liquid.
first, put the mixture in water . salt will dissolve and then allow chalk powder to settle down. Then try decantation.
When you crush chalk, the solid structure of the chalk breaks down into smaller particles. This results in a powder-like substance that is easier to spread and work with.

Chalk is a soft, white, porous limestone composed mainly of calcium carbonate. It forms over millions of years from the shells of tiny sea creatures called coccolithophores that settle to the bottom of the ocean. These shells accumulate and are compressed to form the chalk rock we use.
As the beaker cools down, the thermal energy within it decreases. This results in a transfer of heat from the beaker to its surroundings, causing the temperature of the beaker to drop.
When a beaker is cooled down, thermal energy is transferred from the beaker to the surroundings. The molecules in the beaker lose kinetic energy, which causes the temperature of the beaker to decrease. This transfer of thermal energy continues until the beaker reaches thermal equilibrium with its surroundings.

Both processes involve a solid substance breaking down into smaller particles. In the case of an ice cube melting, the solid water molecules break apart into liquid water molecules. When grinding chalk into a powder, the solid chalk is physically broken down into smaller chalk particles.
An inverted beaker is simply a beaker turned upside down. This position prevents the contents inside the beaker from spilling out or from being contaminated by outside substances. It is commonly used in labs to cover or protect the contents of the beaker.
