Comparing Heat Loss Between A Single Test Tube and Test Tubes in a Huddle Aim I aim to prove whether heat loss is reduced by huddling test tubes, as opposed to the heat loss of a single test tube, which is more exposed to the air. Background Information Controls Variables The number of test tubes. Time taken to carry out the experiment. The number of thermometers. Starting temperature. Amount of water added to each test tube. Final temperature. 15 readings, which are repeated for an average. The number of elastic bands required supporting the huddle. The number of beakers and stands required supporting the test tubes. Prediction I predict that the single test tube is more exothermic than the test tubes in the huddle. This is because, by huddling, a smaller surface area of the test tubes is exposed to the air. Thus, less heat is given off. Heat can be lost in various ways. However, by huddling the test tubes, heat loss via convection and...
