Question

question 1 (1 point) is this a chemical or a physical change? tearing a piece of paper into 100 tiny pieces a physical change b chemical change

Explanation:

Tearing paper only changes its physical form, not its chemical composition. In a physical change, the substance's identity remains the same, just its appearance or state changes. Here, the paper is still paper but in smaller pieces. In a chemical change, a new substance with different chemical properties is formed. Since tearing paper doesn't create a new substance chemically, it is a physical change.

Answer:

a. Physical change
