Answer: Option (b) is the correct answer.
Explanation:
When thermal energy of a substance increases then molecules of the substance start to vibrate more vigorously.
As a result, there will be increase in kinetic energy of particles. Also, force of attraction will decrease between the molecules.
Thus, we can conclude that an increase in thermal energy affect molecules as they begin to vibrate more.
An increase in thermal energy or the temperature of the system affects molecules. An increase in thermal energy increases the vibration of molecules.
What is Thermal energy?
The thermal energy and the motion of particles are proportionally related. The thermal energy or the temperature of the system increases the kinetic energy and the motion of the molecules.
The thermal energy of a system is due to the movement of its constituting particles. When heat is given to a system the motion of the particles is increases, as a result, the thermal energy of the system also increases.
Therefore, option b. an increase in thermal energy affects molecules, increases the vibration of molecules.
