What are reversible and irreversible changes?
Reversible Changes – This is when materials can be changed back to how they were before the reaction took place. E.g. When ice melts to form water. It could be frozen back to ice again. 2. Irreversible Changes – This is when materials cannot be changed back to how they were before.
