What are examples of solidification?

An example of solidification is when cooking oil changes to solid after exposure to cold temperatures. Solidification, also referred to as freezing, is the process by which liquids or fluids change to solids.

Another example of solidification is where milk, water and liquid foods harden when stored in a refrigerator. Just like other physical changes, solidification does not change the chemical identity of the substance. Other instances of chemical change are melting or fusion where solids change to liquids, and sublimation where solids change to gas. Liquid changes to gas in a process called evaporation or boiling while gas changes to liquid in a process called freezing or solidification.
