Specific heat capacity is given by
C= dU/dT J/mole.K
(Note the unit. It's per mole not per kg)
For gases, two specific heat capacities exist, constant pressure and constant volume. For solid and liquids, it's just a single value. Once we are clear with this, let's go ahead to find how much this value is.
According to kinetic theory of gases (Which is found true from experimental values. This theory was first time introduced to us in high school), it is clear that internal energy of a substance is proportional to molecular kinetic energy. More the molecular k.e., more will be the specific heat capacity. Once this concept is understood, let's go in depth.
