I read in a book that as an object gains more energy that it gains more mass. That if an object heats up that it actually starts to get heavier. It said this has not been proven because it is several orders or magnitude away. Say you have a specific amount of energy in a battery in the form of electrons (what battery is used for). Then you have another battery that is dead with no electrons but is heated up with the same amount of energy. Shouldn't the two then be equal in weight according to this? thanks
