Most plastics are actually liquids .... they are just very viscous.
The glass in your window is also a liquid.
A solid has a defined crystal structure. Things like asphalt, plastic, and glass don't have a crystal structure and are therefore liquids. Really think, viscous liquids. As you heat them, they become softer and softer as opposed to melting and changing to a liquid all at once.
When heat is removed from a liquid and it cools, the molecules in the liquid lose energy and slow down. Eventually, the liquid will reach its freezing point and transform into a solid through the process of crystallization.
A liquid becomes a solid when heat is removed. The energy content decreases, and the speed of the particles decrease.
A liquid becomes a solid when heat is removed. The energy content decreases, and the speed of the particles decrease.
Remove enough heat from the liquid, it changes to a solid- known as freezing.
When heat is removed from solids, the particles within the solid lose energy and begin to move less vigorously. As a result, the solid contracts, and its temperature decreases. If enough heat is removed, the solid may reach its freezing point and undergo a phase change, solidifying from a liquid to a solid state. This process can also increase the rigidity and brittleness of the material.

When heat energy is taken from a liquid, the temperature of the liquid decreases, causing the molecules to slow down and come closer together. If enough heat is removed, the liquid can eventually freeze and become a solid.
