This try forbidden was suggested by my Aunt mainly because she heard a illustration about longer lasting batteries through freezing the batteries. This try out was done by using 2 batteries and by using a torch to drain the barrage life. The full(a) taste took approximately 9 weeks. Aim: The aim of this proveation is to test out whether leaving AA batteries in a electric refrigerator or deep-freeze leave alone have a longer life drag than AA batteries that have been leftover out in normal reduce on temperature. It is also to reveal out how cooling affects the chemical reactions inwardly a battery thus in turn, how it effects the higher status of battery life. Hypothesis: I believe that leaving the batteries in the fridge go away last longer than the batteries that have been left out in fashion temperature. Furthermore, the batteries that have been left in the deep-freeze will last even longer. Equipment: 24 AA Eveready batteries Super surd Duty Iytworx Rubber flashlight Light (with 3 Super Bright LEDs) Goliath Sandwich bags Fridge deep freezer Room Kitchen Thermometer Variables: Independent: The temperature in which the battery is stored in i.e. fridge, freezer and room temperature. Dependant: The battery life. Controlled! : stamp battery brand Battery Type (AA) The batteries are Zinc-Carbon not Alkaline The batteries in the experiment are new Same type of...
