The thermal motion means
The thermal motion means
- A. motion due to heat engine
- B. disorderly motion of the body as a whole
- C. motion of the body that generates heat
- D. random motion of molecules
Step-by-step solution
Thermal motion refers to the random, chaotic movement of atoms and molecules in a substance due to their thermal energy. It is a microscopic phenomenon, not macroscopic motion of the body as a whole (option B), not motion caused by a heat engine (option A), and not motion that generates heat (option C; rather, heat is the energy associated with this motion).
