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)

Both (B) and (C)

cv = R/ γ-1

cv/ cp =R

cp - cv = R

Both (B) and (C)

cv = R/ γ-1

cv/ cp =R

cp - cv = R

Engineering Thermodynamics
Coke is produced

When coal is strongly heated continuously for 42 to 48 hours in the absence of air in a closed vessel

From the finely ground coal by moulding under pressure with or without a binding material

By heating wood with a limited supply of air to a temperature not less than 280°C

When coal is first dried and then crushed to a fine powder by pulverizing machine
