Detailed explanation-1: -The thermal energy will flow in that direction until the two objects are at the same temperature. When the two systems in contact are at the same temperature, we say they are in thermal equilibrium.
Detailed explanation-2: -When two bodies at equal temperature are brought in contact with each other then no heat flows between them and they are said to be in thermal equilibrium.
Detailed explanation-3: -Thermal equilibrium is when two substances that had heat transferred between them no longer transfer heat between them because their thermal energy became equal and their temperature became the same.
Detailed explanation-4: -(c) The two objects reach “thermal equilibrium” when both substances are at the same temperature, and their molecules have the same average kinetic energy.
