the sum of all the kinetic energies of all the molecules of an object

the average kinetic energy of the molecules of an object

Answer 1

The correct description of temperature from the given options is:

the average kinetic energy of the molecules of an object.

Temperature is a measure of the average kinetic energy of the particles in a substance, and it reflects the thermal energy within that system.
