Question

You have been hired as an intern for a plastics manufacturing company. When researching several types of plastics​ (Acrylic, HDPE,​ PET) to use for a new bottle​ design, the following facts were determined by a previous intern. Your boss has asked you to check the work of the previous intern. The previous intern listed several values of the specific gravity of PET. Which of the following is not a physically possible specific gravity of the​ plastic? Select all that apply. A. 136 B. 0.84 C. 84 D. 0.00136 E. 1.36 F. 0.00084

Answer 1

As we all aware that plastic floats on the surface of water.

so we can easily assume that specific gravity of plastic could not vary to a

a large extent.so A.136,B.84.are not physically possible specific gravity of

plastic.as these type of material(with sg 84 136)would be detrimental to environment

Again As we know plastic is a solid so 000136 and 0.00084 are also not the

possible specific gravity of plastics.
