While researching a topic, a student has taken the following notes:
- Generally, an object will heat up when twisted.
- The twisting of an object is known as torsion.
- A 2019 study led by Zunfeng Liu and Ray Baughman tested the torsional heating of various fibers.
- When a 0.7-millimeter thick sample of single-ply nickel-titanium (NiTi) wire was twisted, its average surface temperature increased by .
- When a 2.2 millimeter-thick sample of natural rubber fiber was twisted, its average surface temperature increased by .
The student wants to contrast the two samples. Which choice most effectively uses relevant information from the notes to accomplish this goal?
The natural rubber sample used in the 2019 study was thicker than the single-ply NiTi wire sample.
A
In 2019, researchers studied the effect of torsional heating on various fibers, including samples of natural rubber and single-ply NiTi wire.
B
When the fibers were twisted as part of the 2019 study, the surface temperature of both samples increased.
C
Twisting an object will generally cause its temperature to increase, a process known as torsional heating.
D
