Ok, this is my science fair project and what i am doing is getting three small Ziploc bags and then filling each one with water and put a thermometer in each bag and then get 3 large Ziploc bags and fill each one with a certain installation (one with paper, one with cotton,etc.) then, I'm going to put one bag of water in each of the three bags with the different installationI am going to set the bags in a closet and check the temperature of each one later onSo could anybody tell me which one would produce the most heat? and why?
