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.
WebApr 7, 2024 · The concept of entropy was first introduced in 1850 by Clausius as a precise mathematical way of testing whether the second law of thermodynamics is violated by a particular process. The test begins with the definition that if an amount of heat Q flows into a heat reservoir at constant temperature T, then its entropy S increases by Δ S = Q / T.
