I did an experiment where i took a battery from zero degrees celciUs to 60 degrees celcius. I measured the voltage at various points along the way. not this was a 1.5 volt energizer battery. Instead of seeing a decrease in the voltage as the temperature increased (as expected) i saw an increase in voltage.
I have no idea how this could have happened. COuld it be the electroytes - if so how would that work?

the literature on the experiment predicts it will decrease. Many other students found it decreased. I like the idea that it was just more activity. but is that really true?

As the temperature went up, the chemical activity increased and you got more voltage. Did you ever notice on a very cold morning where a car cranks very slowly when you try to start it ?? Same effect. Glad you learned something from your experiment !

Your wrong in your assumption that the battery voltage decreases with an increase in temperature, it's the other way round, Increase temperature, and the voltage increases. Have you ever heated your TV remote control when the battery is failing ?

Normally the higher the temperature of an chemical solution the faster it will work,so u got the right answer.
