Molar heat capacity of water is equilibrium with the ice at constant pressure is :

Options

A. Zero
B. Infinity `(oo)`
C. `40.45KJK^(-1)mol^(-1)`
D. `5.48JK^(-1)mol^(-1)`

Answer

B

Explanation

Ice `iff` water phase change takes place at constant T and P. Hence `DeltaT=0`
`therefore C_(p)=(DeltaH)/(DeltaT)=oo`
