In Second Law of Thermodynamics
I am new to this, or any forum, and therefore I am not familiar with the procedure. At any rate, if I or we get lost, my e-mail address is: I would like to discuss about the 2nd law of thermodynamics. Am I at the right place with the right person? At any rate, I would like to expand on the 2nd law of thermodynamics, as clearly and concisely stated by the Kelvin-Planck statement: "It is impossible to construct a device that, operating in a cycle, will produce no effect other than converting heat completely into work:" This statement prescribes that, if an engine operates in a cycle, it is impossible to convert all the available heat entering the engine into work and some heat will exit the engine. My question is: Is this a prescription for rejecting the unused heat into the external ambient, i.e., outside the cycle? In my opinion, the Kelvin-Planck statement simply prescribes the impossibility of building an engine that can convert the available heat entirely into work in one cycle, but it is silent about what to do of the unused heat. Do you agree? I am particularly interested in the response from Suyog, as he seems to have the proper preparation for an educated reply. Thanks. Emilio
