Question

Heat capacity (C_p ) is 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, heat capacity = 18 × specific heat

or C_p = 18 × c

Specific heat = c = 4.18 Jg^–1K^–1

Heat capacity = C_p = 18 × 4.18 JK^–1 = 75.3 J K^–1
