Determine the change in entropy  $\Delta S\left(inSIunit\right)$ of 100 gm of water when it is heated to the boiling point from room temperature of T=300 K, and it is transformed into vapour at the boiling temperature and atmospheric pressure. It is given that for water :
Specific heat capacity of  water=$4186J/Kg$ ; latent heat of vaporization: L=2.26 MJ/kg. [Take ln (1.24)=0.217]
