Explanation:
According to second law of thermodynamics, for a spontaneous change there will be increase in entropy. So, entropy of a system will always increase as and changes that occur in the entropy in the Universe will always be positive.
Entropy means the degree of randomness.
For example, when ice melts then there then solid form of water will change into liquid form. During this change molecules of ice move away from each other.
As a result, change in entropy will occur.
