Question

Choose the correct relation with reason.

Options

  • Isothermal curve slope = adiabatic curve slope

  • Isothermal curve slope = γ x adiabatic curve slope

  • Adiabatic curve slope = γ x isothermal curve slope

  • Adiabatic curve slope= `1/2` x isothermal curve slope

MCQ

Solution

Adiabatic curve slope = γ x isothermal curve slope

Explanation:

For isothermal process, PV = constant

`((dp)/(dv)) =(gammaP)/V = "slope of adiabatic curve"`

`((dp)/(dv))_"adiabotic"=gamma((dp)/(dv))_"isothermal"`
