Will the caloric value of a lemon battery change after you use electricity?

Will it change and how can you prove it through an experiment. I know how to make a lemon battery but I'm stuck on determining the calorie part of my science project.Will the caloric value of a lemon battery change after you use electricity?
your source of energy in the lemon battery is not the lemon itself, which is merely a conducting electrolyte, but the electrodes. What you could do is weigh the more active metal, leave the lemon battery short-circuited, and then weigh the metal again after a time.



Alternatively, if you can use your battery to make a bulb glow, and you can estimate the power of the bulb, you can work out how fast your battery is generating energy, and work out the calories involved.Will the caloric value of a lemon battery change after you use electricity?
Calories are units of heat energy that are not strictly related to the electrons present in a lemon. The experiment is a good one if you have the time to deplete a lemon of enough electrons to show a change in calories available. I would try this with 7 lemons all hooked up the same day and test 1 each day for 7 days with a bomb calorimeter (look it up, it really isn't a bomb). this will give you the answer you seek. My theory will probably be that the lemon lost no appreciable caloric content. Good luck. P.S. you must provide the same drain to all the ';batteries'; so use equal resistance to make the answer accurate.
