When is thermal equilibrium achieved between two identical objects? A. when one object is colder than the other B. when one objects is hotter than the other C. when both objects have the same temperature D. when the particles in one object have more kinetic energy

Thermal equilibrium is achieved between two identical objects when both objects have the same temperature. For temperature to change in an object, it's constituent molecules vibrate at different rates. The less the v ibrations and collisions, the lower temperature of the object. The state of thermal equilibrium is achieved when the molecules in both objects are v ibrating and colliding with each other at the same rate.

The answer to the question is C which is when both objects have the same temperature. The condition under which two substances in physical contact with each other trade no warmth vitality. Two substances in warm balance are said to be at a similar temperature.
