Question

Heating an ice cube Is it a chemical or physical change? Why?

Answer 1

Explanation:

When you melt an ice cube (H2O), you have a physical change because you add energy. You added enough energy to create a phase change from solid to liquid. ... No chemical changes took place when you melted the ice. The water molecules are still water molecules.

I hope it may help you dear friend ❣
