Thermal Energy and Kinetic Molecular Theory

Which option defines kinetic energy? (1 point)

A. The average energy of particles due to motion
B. The energy required to change a gas into a liquid
C. The average energy released when a liquid becomes a solid
D. The energy an object has because of its motion



Answer :

GinnyAnswer

Final answer:

Thermal energy is the average kinetic energy of particles due to their motion, determining the substance's temperature.


Explanation:

Thermal energy is kinetic energy associated with the random motion of atoms and molecules. It is the average kinetic energy of particles due to their motion. As molecules move faster, they possess greater kinetic energy, leading to higher thermal energy and temperature.
