[Title: NO HEAT] [Verse 1] q equals zero this time Reversible, work changes the state Compress it fast enough No time for heat to touch The system does it alone Adiabatic zone [Pre-Chorus] Gamma is the ratio Cp over Cv Lock that number in Watch what the power law gives [Chorus] PV to the gamma equals constant q is zero, only work comes through PV to the gamma equals constant Adiabatic — that's the name [Verse 2] Squeeze it, temperature climbs Expand it, temperature goes down Pressure and volume locked in phase Power law all the way Fast enough, no exchange Reversible within range Internal energy shifts That's how the work lifts [Pre-Chorus] Gamma is the ratio Cp over Cv Lock that number in Watch what the power law gives [Chorus] PV to the gamma equals constant q is zero, only work comes through PV to the gamma equals constant Adiabatic — that's the name [Bridge] Monatomic, gamma five thirds Diatomic, seven fifths More degrees of freedom you store Softer the curve, that's the law [Final Chorus] PV to the gamma equals constant q is zero, only work comes through Temperature moves, entropy stays Reversible adiabatic all the way
