Crushing chalk is a physical change, not a chemical change. Physical changes alter the form or appearance of a substance without changing its chemical composition. So, when chalk is crushed, it remains the same substance chemically but in a smaller form.

Is a piece of chalk crushed a physical change?
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.
Is making chalk dust a chemical change?
No, making chalk dust is a physical change, not a chemical change. It involves the breaking down of the solid chalk into smaller pieces without altering its chemical composition.
Is breaking a lump of chalk to make powder a chemical reaction?
Breaking a lump of chalk into powder is a physical change, not a chemical reaction. The chemical composition of the chalk remains the same before and after breaking it into powder.
Is pulverized chalk a physical or chemical change?
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.
Is mixing crushed chalk with water a chemical or physical change?
Mixing crushed chalk with water is a physical change. This is because the chalk particles are simply dispersed throughout the water, but no new substances are formed. The mixture can be easily separated back into its original components of chalk and water.

Is crushing a piece of chalk a chemical change or a physical change?
Crushing a piece of chalk is only a physical change. Chemically, it is still chalk.
How does chalk change after it has been shaken?
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.
When you hydrochloric acid and chalk together is it physical or chemical change?
When you mix hydrochloric acid with chalk, a chemical change occurs. This is because the acid reacts with the calcium carbonate in the chalk to form carbon dioxide gas, water, and calcium chloride. This is a chemical reaction that results in the formation of new substances.
If chalk doesn't dissolve in water is it a chemical or physical change?
It is a physical change because the chalk is still chemically the same substance whether it is in solid form or dispersed in water. The molecules in the chalk are not altered by the process of being put in water.
What is the following is a physical property of a substance?
Chalk can be broken into pieces.
When pounding chalk to small bits a physical change or a chemical change?
It's a physical change because it's only changing size and shape, not converting chemicals.
