WebJul 3, 2024 · The First Law of Thermodynamics demonstrates the relationship between internal energy, added heat, and work within a system. The Second Law of Thermodynamics relates to the natural flow of heat … Webmore. You are missing a very important part of the second law. It doesn't say heat cannot transfer from cold to hot. It says it cannot transfer spontaneously from cold to hot. In essence, this is saying that, in a closed system without any external input of energy, heat will not transfer from cold to hot.
