>>>Hi Hilmar,
>>> This should clear up misconceptions regarding Entropy. When the temperature of a quantity of heat energy is reduced to that of its surroundings, its availability becomes zero and the value of its entropy has reached a maximum for the conditions under consideration.

>>I basically agree. Now, while I am not sure about this, I suspect that some forms of energy other than heat may also represent unavailable energy.

>Any sort of radiation, not only light, is most probably lost. Or something as simple as compressing something (gas in a container, a steel spring) and it breaks or the container bursts. The energy was wasted to break the molecular ties in the matter, but cannot be restored. Take chopping wood, or breaking crystals by grinding. The energy used for the breaking can not be restored.
Yes, right, the breaking container would result in the loss of the pressure difference. I thought there was more to it than temperatures, but I wasn't sure about the details. Thanks.
Hilmar.
