SSC MTS EXAM

Detailed explanation-1: -The condition under which two substances in physical contact with each other exchange no heat energy. Two substances in thermal equilibrium are said to be at the same temperature.

Detailed explanation-2: -When there is no temperature difference and the temperature remains constant throughout a system, it is said to be in thermal equilibrium.

Detailed explanation-3: -Thermal equilibrium is established when two bodies are in thermal contact with each other-meaning heat transfer (i.e., the transfer of energy by heat) can occur between them.

Detailed explanation-4: -Thermodynamic equilibrium leads to the large scale definition of temperature. When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the objects.
