π§ Frozen crystals
According to the third law of thermodynamics, when the temperature of a body cools to absolute zero (0K), its entropy reaches its minimum.
For example, let’s take a perfect crystal and start cooling it (lowering its temperature). What will happen?
If the crystal is perfect, its entropy will be zero when the temperature of the crystal reaches absolute zero – 0K. If the crystal is not perfect, there is some disorder in it. If the temperature of the crystal is above 0K, it is expected to have movement of its molecules and disorder.

When the temperature of the crystal rises above 0K, the molecules in it begin to move, creating a disorder (its entropy increases). What will happen when the temperature of the crystal becomes so high that it begins to melt (it has reached its melting point)? Similar to what happens to an ice cube placed in the sun. It begins to melt and turn into a liquid.

The liquid has higher entropy than a solid object. In other words, the liquid is not very tidy.
If we continue to heat it and raise the temperature, what will happen?
Yes, that’s right – the liquid that has already formed will start to evaporate, ie. turns into gas. And gas has even greater entropy and disorder (chaos) than liquid.
