Relation between cp and cv is given by (where cp = Specific heat at constant pressure, cv = Specific heat at constant volume, γ = cp/cv, known as adiabatic index, and R = Gas constant)

Relation between c_p and c_v is given by (where c_p = Specific heat at constant pressure, c_v = Specific heat at constant volume, γ = c_p/c_v, known as adiabatic index, and R = Gas constant)

(A) c_v/ c_p =R

(B) c_p – c_v = R

(C) c_v = R/ γ-1

(D) Both (B) and (C)            (Ans)
