Interpretation Introduction

Interpretation: The value of change in entropy for sytsem, surrounding and total needs to be determined to veruify whether the given transformation is spontenous at -3.75 oC or not.

Concept Introduction:

The change in entropy can be calculated as follows:

  ΔS=nCP,m(H2O(l))lnTfTi

Here, ΔS is change in entropy, CP,m(H2O(l)) is molar heat capacity of water at constant pressure and Ti and Tfare initial and final temperature values.
