Question

Which of the following is a process taking place with increase in entropy?
i) Freezing of water ii) Condensation of steam iii) Cooling of a liquid iv) Dissolution of a solute

Answer 1

I think it was :

( ii ) Condensation of Steam

I hope it help you...

Answer 2

Dissolution of a solute will lead to increase in entropy.

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from  an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

i) Freezing of water :  In this reaction liquid is converting to solid phase. The randomness will decrease and hence entropy will also decrease.

ii) Condensation of steam : In this reaction gas is converting to liquid phase. The randomness will decrease and hence entropy will also decrease.

iii) Cooling of a liquid : In this reaction the temperature of liquid phase decreases and thus kinetic energy decreases. The randomness will decrease and hence entropy will also decrease.

iv) Dissolution of a solute : In this reaction the solid dissociates to ions and  the randomness will increase and hence entropy will also increase.
