Question

1 give an example of a physical change. explain your answer.

Explanation:

An example of a physical change is the melting of ice. When ice (solid water) melts into liquid water, the substance remains water ($H_2O$), and no new chemical substance is formed. The change is only in the physical state (from solid to liquid) due to a change in temperature, and the chemical composition stays the same.

Answer:

An example of a physical change is melting ice. Ice (solid $H_2O$) melts to liquid water; no new substance is formed, only the physical state (solid to liquid) changes, so it is a physical change.
