After a piece of chalk is pounded by a fist or rolling pin or other object it normally get crushed and turns into lumpy powder.
A physical change.
You can change the color of chalk by mixing powdered pigments or food coloring with the chalk dust and a small amount of water to create a paste. Incorporate the paste into the chalk mold and allow it to dry completely before using.
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.
Breaking chalk will change its physical form by creating smaller pieces, which can increase its surface area. This can affect how the chalk interacts with surfaces, making it easier to apply or use for writing and drawing. Additionally, the texture may become rougher at the break points, potentially altering the way it produces dust when used. However, the chemical composition of the chalk remains unchanged.

When pieces of chalk are shaken in a jar with pebbles, they will break down into smaller pieces due to the abrasive action of the pebbles rubbing against them. This process is known as abrasion and will result in the chalk becoming smoother and rounder over time.

Grinding chalk really doesn't change the chalk except to make it into powder. So that makes it a physical change. It is much like ice melting into water.
chemical change
Crushing a piece of chalk is only a physical change. Chemically, it is still chalk.
No, it is a physical, not chemical change.
a place that there is a chalk celebration and they write in chalk everywear iv been in one
Grinding chalk to chalk dust is a physical change because the texture and size may change but the its molecules are still the same.An example of chemical change is burning paper because ash is chemically different from paper.

Yes, crushing a piece of chalk is a physical change because the chalk is still composed of the same molecules before and after being crushed. The change in appearance is only due to the physical state of the substance.
It is pretty much the same. Chalk and limestone are made of the same elements, but to to make chalk they change the limestone a bit. First they change the shape and then make it smooth. I hope that helps!
