Chemistry: Data Analysis for the most suitable material for a backpacker's towel. Method In groups, we tested three different types of material (named pale blue, dark blue and brown) to find out which one would be more suitable as a backpacker's towel. The criteria that would make a good backpacker's towel would be aspects such as a low density, high absorpancy, rapid drying etc. We weighed the fabric before wetting it and weighing it again. We then hung it on some suspended string and let a rotating fan dry them for fifteen minutes. After this time was up, we weighed the materials again in order to work out the drying rate, the absorpancy and the amount of water lost. We then recorded our results in a table (displayed further on) and analysed these to come to a conclusion. Results Fabric Area (cm²) Dry mass Wet mass Mass after drying Absorpancy Water lost Drying rate Wet mass - Dry mass Density Pale blue...
