No, boiled water alone is not sufficient to cook an egg. While boiled water can be used as part of the cooking process for certain egg dishes, such as poached eggs, it is not enough to fully cook an egg from its raw state.
To cook an egg, you typically need a heat source, such as a stove or an oven, to provide direct heat. This allows the egg to undergo chemical changes, denature the proteins, and solidify.
If you want to cook a boiled egg, you would typically place the egg in a pot of cold water, bring it to a boil, and then let it simmer for a specific amount of time, depending on the desired level of doneness (e.g., soft-boiled, medium-boiled, or hard-boiled).
Boiled water alone would not provide the necessary heat transfer to cook the egg properly.
