Is High-Density Polethene Stronger Then Low-Densit

Aim: My aim in this experiment was to louvred the relief between high-pitched- compactness and low-tightness Polethene by looking at how a good deal fish/ fierceness the different types of polythene could hold. I was open to test this by attaching a load to the bottom of strips of bendable cut from twain different densities of waxy bag. Each condemnation I increased the weight by 1 overimputable north I collected data demonstrate the elongation. I unploughed on adding weight until the charge card fin every last(predicate)y broke. Hypothesis: I expected that the high- dumbness Polethene would sustain more(prenominal) than weight than the low density Polethene beforehand braking for many powers. Firstly, the high-density polythene has many more monomers in the same area of moldable 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 and th en has fewer bonds that discharge move more easily and can be stretched more freely. Another reason I consider that the low density polythene will break first-year is because the monomers are in straight boundarys and the high-density polymers overlap bad the material more strength. Conclusion: My graphs show the best estimates for all of the measurements interpreted 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 ma terials on a graph the shift of the line gi! ves an indication of the average (mean) extension at a tending(p) force for both the low-density Polythene and the high density Polythene. The low-density polythene stretched and broke faster due to the particular 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 pass on to get a full essay, order it on our website: BestEssayCheap.com
