The melting of an ice cube is considered both a physical change and a chemical change simply because a chemical change is something burning, so if the ice cube is cold and hot at the same time, it's both a physical change and a chemical change.
its physical change.to explain,the conversion of solid to liquid is physical
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
Explain the difference between chemical change and physical change, and provide examples of each. Define chemical change and physical change, and provide examples to illustrate. Differentiate between chemical change and physical change, and give examples to clarify the distinction.
- Sublimation don't change the molecule; solid iodine or sublimated iodine are iodine. - Slaking of lime transform the calcium oxide in calcium hydroxide. A chemical change occur.
Deductive reasoning or if you work backwards it could be inductive reasoning.
It is physical. The wire changes shape, but it is still made of the same materials.
Breaking of stone is a physical or chemical change? Explain.

both physical and chemical change occur
Both

burning of wood is a chemical change as it produces heat and cutting it into small pieces is a physical change as there is a change in shape and size.
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.

The changes from A to B and from B to C are physical changes. Physical changes do not alter the chemical composition of the substances involved. In this case, the changes are likely related to states of matter or physical appearance, rather than chemical composition.
