Is High-Density Polethene Stronger Then Low-Densit

Aim:
My aim in this experiment was to find the remainder between high-pitched- compactness and low-tightness Polethene by looking at how a good deal weight/force the different types of Polythene could hold. I was open to test this by attaching a weight to the bottom of strips of bendable cut from two different densities of plastic bag. Each condemnation I increased the weight by 1 overimputable north I collected data showing the elongation. I unploughed on adding weight until the plastic fin every last(predicate)y broke.

Hypothesis:
I expected that the high-density Polethene would sustain more than weight than the low density Polethene before braking for many powers. Firstly, the high-density Polythene has many more monomers in the same area of plastic 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 therefore has fewer bonds that can move more easily and can be stretched more freely. Another reason I believe that the low density Polythene will break first is because the monomers are in straight lines and the high-density polymers overlap bad the material 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 an indication of the average (mean) extension at a given force for both the low-density Polythene and the high density Polythene. The low-density polythene stretched and broke faster due to the fact 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 request to get a full essay, order it on our website: Ordercustompaper.com
