Electronic nematicity in iron pnictide materials has been extensively studiedby various experimental techniques, yet its heat capacity anomaly at the phasetransition has not been examined quantitatively. In this work we review thethermodynamic description of nematicity in $Ba(Fe_{1-x}Co_{x})_{2}As_{2}$ usingthe Landau free energy, which defines the behavior of three thermodynamicquantities: the structural orthorhombicity that develops below the nematictransition, the softening shear modulus above the transition, and thediscontinuous heat capacity at the transition. We derive a quantitativerelationship between these three quantities, which is found to hold for a rangeof dopings. This result shows that the nematic transition is exceedingly welldescribed by a mean-field model in the underdoped regime of the phase diagram.
