The normal heat of fusion of water is 18.53 J/mol. Calculate the change of entropy of the system that 1 mole of solid water is changed to liquid water?
Question
Solution 1
To calculate the change in entropy (ΔS) when 1 mole of solid water changes to liquid water, we can use the formula:
ΔS = q/T
where:
- q is the heat absorbed or released during the phase change (in this case, the heat of fusion), and
- T is the absolute temperature (in Kelvin).
