Question

Q.5. Predict in which of the following entropy decreases / increases:
i) A liquid crystallizes into a. solid.
ii) When ice melts.​

Answer 1

Answer:

• Melting ice makes a perfect example of entropy. As ice the individual molecules are fixed and ordered. As ice melts the molecules become free to move therefore becoming disordered. As the water is then heated to become gas, the molecules are then free to move independently through space.

Explanation:

• When a liquid crystallizes into a solid, the molecules attain an ordered state and hence, entropy decreases

Answer 2

Answer:

1) A liquid crystallizes into a solid.

Ans :- entropy decreases.

2) When ice melt.

Ans:- entropy increases.
