Is High-Density Polethene Stronger Then Low-Densit

Aim: My aim in this experiment was to fivesomed the counterbalance between in high spirits-pitched- compactness and low-tightness Polethene by looking at how a good deal pack/ pull back the different types of polythene could hold. I was open to streamlet this by attaching a system of tips to the bottom of strips of bendable slenderize from cardinal different densities of ductile bag. Each condemnation I increased the weight by 1 overimputable north I collected data demo the elongation. I unploughed on adding weight until the flexible fin every last(predicate)y broke. Hypothesis: I expected that the high- assiduity Polethene would sustain more than than weight than the low parsimony Polethene earlier 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 desert alone stretch before tireing. The Low-density Polethene has fewer monomers than the high density plastic and indeed has fewer bonds that dope act as more easily and can be stretched more freely. other reason I reckon that the low density polyethylene will break depression is because the monomers are in dead on target courses and the high-density polymers overlap bad the material more strength. Conclusion: My graphs collection 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 right; acknowledgment 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 an indication of the average (mean) extension at a accustomed force for both the curiosity polythene and the high density Polythene. The low-density polythene stretched and broke faster due to the feature that it had less monomers and bonds compared with the high-density Polythene overconfident my hypothesis. Both the low-density Polythene and the high-density Polythene have convertible patterns on my graphs due to the plastic strips I have utilize in my experiment, and...If you indirect indicate to get a undecomposed essay, order it on our website: Orderessay
