MCQ

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

Answer

Random motion of molecules

Explanation:

Whenever a system absorbs heat from the surroundings or when we supply thermal energy to a system, the internal energy of the system increases.

The heat absorbed increases the kinetic energy of the molecules causing them to move randomly.
