<span>If you measured all the energy related to motion and all the stored energy in the particles of a substance, you would be measuring thermal energy. The correct option among all the options that are given in the question is the last option or option "C". I hope that the answer has come to your great help.</span>
Thermal energy of the system or internal energy of the system is defined as the sum of kinetic energy of all the molecules of the system
As we add the kinetic energy of all the molecules then the sum of this kinetic energy is related to the temperature of the system
It is given as
so here we can say that thermal energy would be the sum of kinetic energy of all the system molecules and it measures the energy related to motion of the system molecules
Well what you need to do in order to know that is doing the following procedure: <span> n sin (theta) = 1 where n = 1.5 </span> <span>theta = arcsin(1/n) = 41.8. </span>so the angle will be 41.8 degrees
