PLEASE HELP!!!! Suppose an experiment is designed to test the durability of batteries in different conditions. All of the batteries tested are double-A (AA) Brand X. All sets of batteries are preconditioned in different environmental conditions for exactly 168 hours (1 week). Set 1: 0°C (freezing point of water) Set 2: 24°C (approximately room temperature) Set 3: 37°C (approximately body temperature) The batteries are then continuously used to power identical mechanical drummer toys. As long as the toy keeps drumming the battery is considered functional.

    The drumming time for each toy is measured as an indication of battery durability. In this experiment, which condition is not controlled? temperature brand of batteries test for durability type of battery (battery size)

    the condition not controlled is the variable that you are looking for since our tests already control the temperature(0,24,37), brand of batteries (Brand X), and type of battery (Double A), then it has to be the test for durability
