| Oct 12, 2022 at 10:38 | comment | added | GiorgioP-DoomsdayClockIsAt-90 | @BobD No, I mean that the temperature of the whole system differs from the thermostat temperature. | |

| Oct 11, 2022 at 12:38 | comment | added | GiorgioP-DoomsdayClockIsAt-90 | @BobD Then, you should be able to derive in some way from the theory that during an isothermal change of volume, there is a macroscopic difference in temperature between the system and reservoir. | |

| Oct 11, 2022 at 10:39 | comment | added | Bob D | Frankly, I don’t see how 1-4 eliminates the requirement for a temperature difference in order for energy transfer in the form of heat, if that’s what you are saying. To me it is simply another way of demonstrating rhe equivalency of the outcome of heat and work demonstrated by Joule with stirrer instead of compression work | |

added a sentence to add another argument to the usefulness of a definition of heat not explicitly based on differences of temperatures.
