Question

What is the entropy change (in `JK^(-1)mol^(-1)`) when one mole of ice is converted into water at `0^(@)C`?
(The enthalpy change for the conversion of ice to liquid water is `6.0KJmol^(-1)` at `0^(@)C`)

Answer 1

We know that for the process of fusion,
`H_(2)O(s)hArrH_(2)O(l)`
`DeltaS_(fusion)=(DeltaH_(fusion))/(T_(f))`
`=(6xx1000)/(273)=21.98J" "K^(-1)mol^(-1)`.
