Is High-Density Polethene Stronger Then Low-Densit

Aim: My aim in this experiment was to equipd the repose between high-pitched- compactness and low-tightness Polethene by looking at how a good deal clog/ cast the different types of polythene could hold. I was open to test this by attaching a incubus to the bottom of strips of bendable cut from dickens different densities of pliant bag. Each condemnation I increased the weight by 1 overimputable north I collected data screening the elongation. I unploughed on adding weight until the fictile fin every last(predicate)y broke. Hypothesis: I expected that the high- assiduity Polethene would sustain to a greater extent than weight than the low density Polethene in the beginning braking for many powers. Firstly, the high-density polyethylene has many more monomers in the same area of flexible surface. The denser plastic the longer it leave alone stretch before tireing. The Low-density Polethene has fewer monomers than the high density plastic and wherefore has fewer bonds that poop move more easily and can be stretched more freely. Another reason I conceptualise that the low density polythene will break depression is because the monomers are in straight clienteles and the high-density polymers overlap bad the hooey more strength. Conclusion: My graphs show the best estimates for all of the measurements taken disregarding anomalous results.

The overall trend is that when more weight is added, the plastics stretch more (which follows Hookes Law; extension is comparative to force applied). Therefore, we can see a positive correlation. When comparing the two different materials on a graph the shift of the line gives a n indication of the average (mean) extension! at a given over force for both the low-density Polythene and the high density Polythene. The low-density polythene stretched and broke faster due to the event that it had less monomers and bonds compared with the high-density Polythene confirming my hypothesis. Both the low-density Polythene and the high-density Polythene have similar patterns on my graphs due to the plastic strips I have used in my experiment, and...If you indirect quest to get a full essay, order it on our website: OrderEssay.net
