%�쏢 The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. In this sense thermodynamics is a meta-theory, a theory of theories, very similar to what we see in a study of non-linear dynamics. b�n�p����L6����^H��}+�m%�@�1���D��"M���=�O��`Y�&y��Ј%����],�kI�$�}���t��e��x+~�۷�h���Z�]to֗]��>IXˡ stream The First, Second, and Third Law of Thermodynamics (ThLaws05.tex) A.T.A.M.
