metal melting is a reversible change because as soon as you make the melted metal and freeze it, it might not come back the way it was but at least it is still the same metal material that you had.
because when you melt an iron nail, It's still that iron nail, it's just in a different form. An example of a chemical change would be malting sugar, because When its melted, it's a completely different thing.
Irreversible examples: Burning a piece of paper, baking a cake, digesting food, rusting of iron, breaking a glass. Reversible examples: Melting ice into water, boiling water into steam, freezing water into ice, dissolving sugar in water, compressing a gas into a liquid.
solidify is an irreversible
After melting, ice will turn into water. This transition is reversible, meaning the water can freeze back into ice if the temperature drops below its freezing point.
Rusting of iron is a chemical change because it involves a reaction with oxygen to form iron oxide. Melting of iron is a physical change because it does not involve a change in the chemical composition of the iron.
yes!
yes
Yes it is
Yes it is
The melting of a candle is a reversible change because the solid wax can be cooled and solidified again to form a new candle.
yes it is. because you can freeze it and melt it
because when you melt an iron nail, It's still that iron nail, it's just in a different form. An example of a chemical change would be malting sugar, because When its melted, it's a completely different thing.
Iron sulfide is a chemical compound. A process or reaction may be reversible or irreversible; a compound isn't.
1535 degree melting of iron
Melting is a reversible change of state, whereas a chemical change is irreversible.
Freezing water is reversible because you can get it back to its original state by melting it - it turns back into water.
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
