Question

Heat capacity `(C_(p))` in an extensive property but specific heat (c ) is an intensive property . What will be the relation between `C_(p)` and c for 1 mol of water ?

Answer 1

For water, molar heat capacity `(C_(p)) = 18 xx `specific heat
`:. C_(p)= 18 xx c`
But specific heat of water , `c=4.18 J g^(-1) K^(-1)`
`:. `Heat capacity , `C_(p) =18 xx 4.18 JK^(-1) mol^(-1) = 75.3 JK^(-1) mol^(-1)`
