Entropy:
Entropy can be defined as the measurement of randomness or disorderness in the thermodynamic system.
As we know that the degree of randomness or disorderness is more in gaseous phase then in liquid and solid phase therefore the entropy of the gaseous phase system is more.
Order of decreasing entropy:
Sgas > Sliquid > Ssolid
So, if the randomness of the system increases, the entropy of the system will increase and if the randomness of the system decreases the entropy of the system decrease.
