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 sample of ethylene propylene diene monomer (EPDM) rubber fiber was twisted, its average surface temperature increased by 12°C.
- When a sample of natural rubber fiber was twisted, its average surface temperature increased by 15.3°C.
The student wants to emphasize a similarity between EPDM rubber and natural rubber fibers. Which choice most effectively uses relevant information from the notes to accomplish this goal?
In 2019, two research teams observed the effects of torsional heating on various fibers, including EPDM rubber and natural rubber.
A
Twisting an object will generally cause its temperature to increase, a process known as torsional heating.
B
Researchers determined that when the fibers were twisted, the average surface temperature of natural rubber increased more than that of EPDM rubber.
C
Both EPDM rubber and natural rubber fibers heat up when twisted, according to a 2019 study.
D
