I'm conducting an experiment where I change the temperature of the sulfuric acid in a lead acid storage cell. My one question in controlling the variables is that should I let the electrodes also change in temperature, or should I keep them at room temperature and measure the cell potential? Does it even matter at all?
What I'm guessing is that a change in temperature affects the resistance of a metal, which would then affect the ability of the electrodes to transfer the electrons involved; therefore, the electrodes should be kept at room temperature.
If I should do one or the other, could someone explain to me why?
