No, it is not.
No, burning a candle is not reversible. When a candle is burned, the wax is melted and the wick is consumed, resulting in irreversible changes to the candle's structure.
No, burning wax is an irreversible change. When wax is burned, it undergoes a chemical reaction that changes it into different substances (carbon dioxide, water vapor, and heat) that cannot be easily reversed.
No, it is not.
yes!
Wax melting is a reversible physical change, not a chemical reaction. When wax melts, it changes from a solid to a liquid state due to the application of heat. Once the heat is removed, the liquid wax will solidify back into a solid form without undergoing any chemical changes.
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.
It is a physical change, from a solid to a liquid. The chemical composition of the wax remains unchanged.
Yeah, definitely. Just wait.
The wax of the candle melts and then rehardens. This is a physical change and reversible
Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
All physical changes are reversible.
Yes, wax is reversible through processes like melting and solidifying. This property allows wax to be reused multiple times for different purposes, making it a versatile material in various applications such as candle making and sculpting.
