Dissolving sugar in water results in an increase in the entropy.
Hence, Option (D) is correct answer.
<h3>What is Entropy ?</h3>
Measurement of randomness of a system is called entropy. It is an extensive property. It is a state function. Unit of entropy is JK⁻¹ mol⁻¹.
Now lets check all options one by one
Option (A): Freezing water
Freezing water decreases the entropy because here second law of thermodynamics does not violate.
So it is incorrect option
Option (B): Cooling water
Cooling water does not increases entropy because entropy increases when solid melts to give liquid.
So it is incorrect option
Option (C): Condensing water vapour
In Condensing water vapour the temperature of liquid phase decreases and thus kinetic energy decreases. The randomness will decrease and hence entropy will also decrease.
So it is incorrect option.
Option (D): Dissolving sugar in solute
In dissolving sugar in solute the solid dissociates to ions and the randomness will increase and hence entropy will also increase.
So it is correct option
Thus from the above conclusion we can say that Dissolving sugar in water results in an increase in the entropy.
Hence, Option (D) is correct answer.
