$${\left( {\frac{{\partial {\text{H}}}}{{\partial {\text{T}}}}} \right)_{\text{P}}}$$ is the mathematical expression for
A. CV
B. Entropy change
C. Gibbs free energy
D. None of these
Answer: Option D
Solution(By Examveda Team)
By the definition of $${C_P}$$ we can write $${C_P} = \mathop {\lim }\limits_{\delta T \to 0} {\left( {\frac{{\delta Q}}{{\delta T}}} \right)_P}.$$Under constant pressure process and by first law of thermodynamics
$$\eqalign{ & Q = dH \cr & \Rightarrow {\left( {\frac{{\partial H}}{{\partial T}}} \right)_P} = {C_P}. \cr} $$
