Baseboard heaters are basically electric resistance heaters

Baseboard heaters are basically electric resistance heaters and are frequently used in space heating. A homeowner claims that her 5-year-old baseboard heaters have a conversion efficiency of 100 percent. Is this claim in violation of any thermodynamic laws? Explain.

Solution

Solution:

NO

This is not the violation of any thermodynamic laws because any of the thermal laws do not say that conversion efficiency cannot be 100% . Therefore the claim made by the homeowner can be absoluetly true without any violation to thermodynamic laws.
