What is the thermal energy of an object?
a. its total temperature
b. the total potential energy of its particles
c. the total kinetic energy of its particles
d. the total kinetic and potential energy of its particles

I did the quiz, (D) "The total kinetic and potential energies of its particles" is correct.

Option (D) is correct. The thermal energy of any object is the sum of the kinetic energy as well as the potential energy of the object.

Explanation:

The total energy of the object at a particular temperature is defined in terms of the two parameters. The energy of the particles is given as the kinetic energy and the potential energy is due to the amount of heat stored in the object.

The object has the vibration energy stored in it and this energy of the object increases as the heat energy of the object is increased. Whereas the potential energy of the object is due to the amount of heat contained by the object.

The total thermal energy of the object always remains constant as the energy of the system is always conserved. The sum of the total amount of kinetic energy and the potential energy of the object remains constant and it is termed as the thermal energy of the object.

Thus, Option (D) is correct. The thermal energy of any object is the sum of the kinetic energy as well as the potential energy of the object.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
