Question 10 of 25
Which of the following statements are true of thermal energy and kinetic
energy?
Check all that apply.
A. The motion of all the molecules or atoms is kinetic energy.
B. The motion of one molecule or atom is its thermal energy.
C. The motion of all the molecules or atoms is thermal energy.
D. The motion of one molecule or atom is its
hinetic energy.

Answer :

Based on the statements provided, the correct answers are: A. The motion of all the molecules or atoms is kinetic energy. Explanation: Kinetic energy is the energy of motion. In any substance, the particles (molecules or atoms) are constantly in motion, which means they possess kinetic energy due to their movement. C. The motion of all the molecules or atoms is thermal energy. Explanation: Thermal energy is the total kinetic energy of the particles within a substance. Since all the molecules or atoms are in motion (kinetic energy), the collective kinetic energy of all particles contributes to the substance's thermal energy. Therefore, both statements A and C are true regarding the relationship between thermal energy and kinetic energy.
