If I ever write a paper that requires some reference to thermodynamics, these are the versions I will use!Courtesy of Dr. Sam B. Knapp, PhD (My wife's dad)...
First Law of Thermogoddammits: You can't get something for nothing
Second Law of Thermogoddammits: You can only break even at absolute zero
Third Law of Thermogoddammits: You can't get to absolute zero
You are absolutely correct about closed systems. I think thermodynamic scientists and engineers like to call them Isolated Systems.More seriously, the second law of thermodynamics applies to closed systems. Energy from the sun and from cosmic background radiation continues to enter our atmosphere, so it must be considered as part of the system for thermodynamics purposes.
