In an ideal situation where no heat energy is produced, what is the
relationship between the chemical energy provided by the battery and the
electrical energy produced according to the law of conservation of energy?
a the chemical energy should be less than the electrical energy.
b the chemical energy should be equal to the electrical energy.
c the chemical energy should be more than the electrical energy.
d none of the above

The corect answer is B The chemical energy should be equal to the electrical  energy.

Explanation:

Law of conservation of energy is the first law of Thermodynamics which state that  the total amount of energy of the Universe is fixed.Energy cannot be created nor destroyed.Energy can only be transformed from one state to another state.

       From the study of the first law of Thermodynamics it can be said that the correct statement is the chemical energy should be equal to the electric energy.
