Question

When the chalk is converted to powdered chalk, what type of change occurs?

• A. Chemical change
• B. Physical change
• C. Both physical and chemical change
• D. No change

Answer 1

The correct option is B Physical change

Conversion of chalk to chalk powder is a physical change as there is no chemical reaction involved in it. The physical state of the chalk remains the same (solid), and chalk powder can be converted back to chalk.
