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. Physical actions, such as changing temperature or pressure, can cause physical changes. No chemical changes took place when you melted the ice.Is melting a chemical change?
While chemical change is when you have a substance that gets transformed into 1 or more different substances. So melting the ice will make it go back to water, melting iron will make it liquid iron … Thus, melting is a physical change.What is a chemical change of matter?
