Polymer Properties Question

[360modina]

Tell me what your ideas are for this multiple choice question

Compared to semiconductors, metals, and ceramics, polymers:

a) have lower melting points
b) tend to have lower densities
c) deform plastically to a higher extent
d) have lower electrical conductivity
e) all of the above
f) a, b, & c
g) a, b, & d

As of now I'm 99% sure that a is true, polymer tend to melt easily. I'm actually sure that b is true also.

do polymers (I'm assuming things like plastics, but there are also natural and biopolymers) conduct electricity? What about metals, ceramics and semiconductors?

What does plastic deformation invlove? Which property of a material determines its plastic deformation?

I think c is mostly true but I'm not sure about d

My ideas for this multiple choice question are that e) all of the above is the correct answer. Polymers generally have lower melting points compared to semiconductors, metals, and ceramics. They also tend to have lower densities, making them lighter and more flexible. Additionally, polymers can deform plastically to a higher extent, meaning they can change shape without breaking. And finally, polymers have lower electrical conductivity compared to the other materials listed. Therefore, the correct answer would be e) all of the above.
