NEET Physics Thermodynamics Questions Solved


The slopes of isothermal and adiabatic curves are related as -

(1) Isothermal curve slope = adiabatic curve slope

(2) Isothermal curve slope = γ × adiabatic curve slope

(3) Adiabatic curve slope = γ × isothermal curve slope

(4) Adiabatic curve slope = 12× isothermal curve slope

(3) For Isothermal process PV = constant

dPdV=PV= Slope of Isothermal curve

For adiabatic PVγ= constant

dPdV=γPV= Slop of adiabatic curve slope

Clearly, dPdVadiabatic=γdPdVIsothermal
