The process of heat flow between hotter and colder gases remains continued until all the molecules have equal:

Explanation

Heat flow between hotter and colder gases continues until all the molecules have an equal average translational kinetic energy due to the principle of thermal equilibrium. In this state, there is no net transfer of heat between the gases, as they reach the same temperature. The process continues until thermal equilibrium is achieved, ensuring that energy is distributed uniformly among the molecules, resulting in a balanced and stable system.
