No discontinuity is observed.

WebSpecific heat (C) is the amount of heat required to change the temperature of a mass unit of a substance by one degree. Isobaric specific heat (Cp) is used for substances in a constant pressure (ΔP = 0) system. Isochoric specific heat (Cv) is used for substances in a constant-volume, (= isovolumetric or isometric) closed system.
