Entropy change is the randomness of the thermodynamic system. The change in the entropy when the water is condensed is 1573 J/K.
An entropy change is a product of mass and the ratio of the enthalpy of vaporization to the temperature.
Given,
Enthalpy of vapourization = 2257 J/gK
The temperature in kelvin = 373 k
The change in entropy is calculated as:
[tex]\begin{aligned} \rm \Delta S &= \rm m (\dfrac{\Delta H_{vap}}{T})\\\\&= 260 (\dfrac{2257}{373})\\\\&= 1573.24\;\rm J/K\end{aligned}[/tex]
Therefore, the change in entropy is 1574 J/K.
