SUMMARY
100 watts of electricity can indeed boil a liter of water in an insulated container, such as one using aerogel insulation or a partial vacuum. The discussion emphasizes the distinction between power and energy, clarifying that watts measure power (J/s) rather than heat. Once the container reaches the boiling point, the insulation will help maintain the heat, preventing significant heat loss to the environment. Thus, under optimal conditions, 100 watts is sufficient to achieve boiling in a well-insulated setup.
