The process of heat flow between hotter and colder gases remains continued until all the molecules have equal:
Correct answer: A. Average translational kinetic energy
- A. Average translational kinetic energy
- B. Average rotational kinetic energy
- C. Average translational potential energy
- D. Average vibrational kinetic energy
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.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
