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?
A
In 2019, two research teams observed the effects of torsional heating on various fibers, including EPDM rubber and natural rubber.
B
Twisting an object will generally cause its temperature to increase, a process known as torsional heating.
C
Researchers determined that when the fibers were twisted, the average surface temperature of natural rubber increased more than that of EPDM rubber.
D
Both EPDM rubber and natural rubber fibers heat up when twisted, according to a 2019 study.
