• A)Isotherm: ;Adiabat: : A is both an isotherm and an adiabat.
• B)Isotherm: ;Adiabat: : B is an isotherm,A is an adiabat.
• C)Isotherm: ;Adiabat: : A is an isotherm,B is an adiabat.
• D)Isotherm: ;Adiabat: : B is both an isotherm and an adiabat.
• E)cannot answer without additional information about the starting temperature.
