THE EFFECT OF TEMPERATURE ON BATTERY VOLTAGE. Alex Petronio and Jackson Evert. The purpose of this experiment was to identify the relationship between the temperature and voltage of a galvanic cell. To accomplish this, two cells, one using zinc sulfate and copper sulfate, and the other using iron sulfate and nickel nitrate, were made and tested at temperatures ranging from 4° C to 42.8° C, and the voltages measured. The results were inconsistent; the zinc sulfate and copper sulfate cell was not affected by the temperature change, but the iron sulfate and nickel nitrate cell was less effective at warmer temperatures. This implies that the effect that temperature has is dependent on the materials used in the cell. To identify the nature of this relationship, cells using different substances should be studied across several temperatures.
