Question

chemical or physical? glass breaking into tiny shards

Explanation:

A physical change is a change in the form or state of matter without a change in its chemical composition. When glass breaks into tiny shards, its chemical makeup (silica - based compounds) remains the same. It is just changing its physical form from a single piece to multiple pieces. A chemical change would involve a change in the substance's chemical bonds and result in a new substance being formed. Since no new substance is formed when glass breaks, it is a physical change.

Answer:

Physical Change
