Answer 1

To determine which equation shows a physical change, we need to consider the nature of the changes represented by each equation.

A physical change involves a change in the state or appearance of a substance without altering its chemical composition. Common examples include changes in state (like melting or freezing), changes in shape, and dissolving.

If you can provide the equations, I can help identify which one(s) show a physical change.
