It’s all based on you but yours could be anything hard you went through and how you overcame it. Also say how it made you the person you are today
Polyethylene is synthesized from ethylene which is a compound derived from natural gas or petroleum. It’s essentially a thermoplastic, implying that it can be molten and remolded into the desired shape making it reusable and cost-effective. Of all the different kinds of plastics produced around the world, polyethylene is the most common and significant.
Polyethylene is manufactured in three different forms namely:
Low Density Polyethylene (LDPE),High Density Polyethylene (HDPE) andLinear Low Density Polyethylene (LLDPE),
Each of these three plastics has different applications ranging from containers, packaging and films to buckets and bottles.
Hope it helps you...
Q = M * C *ΔT
Q / <span>ΔT = M

C = 1137 J / 140 * 36.2
C = 1137 / 5068
