    13.4: Entropy Changes in Reversible Processes

    1. korollar 03 Sep 2021
      ΔScold = q/Tcold

      Doesn't it say above that this definition is only valid for reversible processes?

      ΔSuniv approaches zero will not occur spontaneously as written but will occur spontaneously in the reverse direction

      I don't understand this sentence. Is the ice reversibly drawing in heat from the environment an example that would fit this description? Does that then mean that ice spontaneously looses heat to the environment?!

      absorbed reversibly from the surroundings

      So, if I understand correctly, this heat transfer is not due to the temperature difference between the ice and the warmer block - which would be the mechanism referred to in the irreversible example below?
