Can 100 Watts of Electricity Boil a Liter of Water in an Insulated Container?

Click For Summary
100 watts of electricity can indeed boil a liter of water over time, especially when using effective insulation like aerogel or a partial vacuum. The discussion emphasizes that watts measure power, not energy, clarifying that power equals energy divided by time. Once the system reaches a steady state, the heat generated will not travel back into the electric cable but will be maintained within the insulated container. The second law of thermodynamics is acknowledged, but the focus remains on the efficiency of heat retention in an insulated environment. Overall, with adequate insulation, 100 watts is sufficient to boil water in a small container.

I would like to know if 100 watts of electricity can boil a liter of water over time. If the vessel containing the water is insulated say with arogel insulation or a partial vacuum. The reason for asking this question, in the second law of thermodynamics it says that "heat goes from a region of high heat to a region of less heat". So will the heat in the container once it has reached 100 watts start traveling into the electric cable, or will the the 100 watts of electricity no longer travel into the container, or will the heat be maintained at 100 watts

You should go back to basics as the watt is not a unit of energy but a unit of power such that power = energy / time, more explicitly J/s. So you cannot talk of 100 watts of heat in the container.

Temperature is also not heat.
 
...however, 100w can certainly boil a small, insulated container of water.
