Answer:

a solid is more ordered than a liquid

Step-by-step explanation:

The entropy is defined as degree of randomness. More the disordered system, more the entropy of the system as compared to a system with same compound and more ordered arrangement.

In case of gas, liquid and solids, the molecules move randomly here and there in gas, while they are more ordered in liquid as compared to gas, and in gas the particles are almost fix. They do not show any translation motion.

Thus solids are more ordered than a liquid and thus have lower entropy.
