Which of the following processes has an increase in entropy?

a) boiling a pot of water
b) freezing a sample of water
c) filtering sand out of a sample of water
d) synthesizing water from hydrogen and oxygen

Option (A) is the correct answer.

Explanation:

Entropy is defined as the degree of randomness. This means that more is the temperature provided to a system more rapidly its molecules will move.

Therefore, molecules of water in a boiling pot will show maximum randomness. As a result, boiling a pot of water has an increase in entropy.

Thus, we can conclude that out of the given options processes that has an increase in entropy is boiling pot of water.

the answer is barium and copper bromide
