Entropy of naphthalene:

Consider naphthalene C10H8 at atmospheric pressure.

It is a solid with a melting point at 80.1 degrees Celsius and a boiling point at 218 degrees Celsius. The latent heat of fusion is 19,123 kJ / mol. The molar heat at constant pressure of solid naphthalene has a functional temperature dependence (in K) which is linear. Its value is 0 at T = 0 K and 188.41 J / mol-K at T = 317.15 K. The molar heat at constant pressure of liquid naphthalene has a functional temperature dependence (in K) which is also linear. At T = 357.91 K, it is 219.34 J / mol-K and at T = 460.25 K, it increases to 317.47 J / mol-K.

Find the entropy change that 1 kg of naphthalene undergoes when heated from 0 to 100 degrees Celsius at atmospheric pressure.
