Entropy by definition is the degree of randomness in a system.

If we look at the three states of matter: Solid, Liquid and Gas, we can see that the gas particles move freely and therefore, the degree of randomness is the highest.

For liquid state, still the particles are moving but less freely than the gas particles and more than the solid particles.

Therefore, #S_(gas)">>"S_(liquid)>S_(solid)#
