[Verse 1] Doesn’t matter how I moved Every path I took is removed Only what I am remains State defined, no hidden chains Heat enters through T dS Work appears in p dV Two distinct and coupled terms Set the change in energy [Pre-Chorus] No extra terms to justify Everything is quantified [Chorus] dU equals T dS minus p dV Heat and work together, full accounting, no degree dU equals T d S minus p dV Every path collapses to the same identity [Verse 2] Temperature defines the scale Entropy counts what is real Pressure sets the sign of work Volume change defines the term Reversible or not the same Initial, final fix the change No dependence on the way Only where the system stays [Pre-Chorus] No approximation left to hide All relations quantified [Chorus] dU equals T dS minus p dV Heat and work together, full accounting, no degree dU equals T dS minus p dV Every path collapses to the same identity [Bridge] Hold S fixed U shifts with Vee Hold Vee fixed U shifts with S Two directions same control Different paths one total Add one term extend the frame mu dN same equation [Break] T dS minus p dV [Final Chorus] dU equals T dS minus p dV Heat and work together, full accounting, no degree dU equals T dS minus p dV Every path collapses to the same identity
