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.
is positive when randomness increases and
is negative when randomness decreases.
When the solid changes to liquid to gas ,the randomness of particles increases and hence is positive and thus the entropy increases.
