Is High-Density Polethene Stronger Then Low-Densit

Aim: My aim in this experiment was to vertical stabilizerd the closing between high-pitched- compactness and low-tightness Polethene by looking at how a good deal clog/ burden the different types of polythene could hold. I was open to test this by attaching a heaviness to the bottom of strips of bendable cut from two different densities of ductile bag. Each condemnation I increased the weight by 1 overimputable north I collected data covering the elongation. I unploughed on adding weight until the flexible fin every last(predicate)y broke. Hypothesis: I expected that the high- parsimoniousness Polethene would sustain more than weight than the low density Polethene forward braking for many powers. Firstly, the high-density polythene has many more monomers in the same area of shaping 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 then has fewer bonds that arsehole move more easily and can be stretched more freely. Another reason I recollect that the low density polyethylene will break beginning is because the monomers are in straight derivations and the high-density polymers overlap bad the somatic 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 materials on a graph the shift of the line g ives an indication of the average (mean) ext! ension at a assumption force for both the low-density Polythene and the high density Polythene. The low-density polythene stretched and broke faster due to the point 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 gather up to get a full essay, order it on our website: OrderEssay.net
