How will breaking chalk change the chalk?
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.
Is crushing of chalk irreversible?
Yes, the crushing of chalk is an irreversible process. When chalk is crushed, its structure is permanently altered, breaking it down into smaller particles. This physical change cannot be reversed, as the original larger pieces of chalk cannot be restored to their initial form.
What is sublimationIs grinding of chalk a physical changewhat is its indicator of change?
Sublimation is the process where a solid changes directly into a gas without passing through the liquid state, such as dry ice turning into carbon dioxide gas. Grinding chalk is a physical change because it alters the size and shape of the chalk without changing its chemical composition. The indicator of this change is the ability to still identify the chalk as the same substance, despite its physical form being altered.
