no don't be silly. it is a physical change because you are able to change it back to its original state. :)

No, making an ice lolly is not a chemical reaction. It is a physical change where liquid ingredients freeze to form a solid. The change is reversible as the ice lolly can melt back into liquid form.
No, melting an ice lolly is a physical change, not a chemical reaction. The change from solid to liquid state is due to the absorption of heat energy, causing the ice lolly to change phase without any change in its chemical composition.
The melting of an ice lolly is considered an irreversible process. Once the ice lolly melts and turns into liquid form, it cannot be easily reversed back to its original solid state.
An ice lolly will melt the fastest at temperatures above freezing, usually around room temperature (20-25°C). This is because the heat from the surrounding environment will transfer to the ice lolly, causing it to melt.
An ice lolly starts in a solid state but can change shape as it melts due to heat from outside sources or ambient temperature.
