Abstract

RANKINE'S “Thermodynamic Function Phi;” (defined by t.dΦ=dH) is now called “Entropy Φ.” The state of a pound of stuff which has only fluid stress and strain is completely defined when we know the values of any two of p, v, t, E or Φ [during change of state the two must not be merely p and t] where E is the intrinsic energy and Φ is the entropy. When we say that E returns to its old value if we bring the stuff to the same state again, we state the first law of thermodynamics in its most general form. When we say that p returns to its old value, we state the second law of thermodynamics in its most general form.
