Question

question 5 (5 points) \\ saved which of the following is always a chemical change? \\ \bigcirc magnetizing a metal \\ \bigcirc expansion of a gas \\ \bigcirc apple rotting \\ \bigcirc melting ice \\ \bigcirc dissolving sugar in water

Explanation:

To determine a chemical change, we check for new substance formation. Magnetizing a metal (physical, no new substance), gas expansion (physical, volume change), melting ice (physical, phase change), dissolving sugar (physical, solvation). Apple rotting involves decomposition (new substances like CO₂, fungi), so it's a chemical change.

Answer:

Apple rotting
