Determine the change in entropy `DeltaS` (in SI unit) of 100 gm of water when it is heated to the boiling point from room temperature of T=300 K, and its is transformed into vapour at the boiling temperature and atmospheric pressure. It is given that for water the molar heat capacity C= 75.4 J/(mol-K), latent heat of varporization L= 2.26 Mj/kg.
(Take ln(1.24) = 0.217)`

Explanation

`DeltaS = nC ln T_(b)/T + (mL)/T_(b) = 697 J//K`
