Bubbles Up: A Science Experiment on Density Density is the measure of the quantity of some physical property [usually mass] per unit length‚ area‚ or volume (YourDictionary.com). How does temperature affect density? Do items become denser after being frozen? It is well known that water becomes denser when it ’s temperature lowers until its freezing point. Does this principle apply to oil; and if so‚ which kinds? This question easily applies to real world problems. For example‚ when there is an

advantages and disadvantages in using a TLC sheet of a different length. For example‚ it becomes a disadvantage if the TLC sheet in this lab was 5 cm shorter. If this were the case‚ then (Sample A) would not have shown up or the second spot of unknown substance #3. Moreover‚ the unknown substance‚ which consists of (Sample A‚ would be incorrectly identified as a pure substance and/or as consisting of only (Sample D). Contrary to using a shorter TLC sheet‚ a longer TLC sheet might allow more substances
