What is the end result of the process known as freezing?

1. Liquid to gas

2. Gas to solid

3. Gas to liquid

4. Liquid to solid

The correct answer is: Liquid to solid

The correct answer pertains to the transformation that occurs when a substance changes from a liquid state to a solid state, a process known as freezing. This process typically occurs when the temperature of the liquid drops to its freezing point, causing the molecules to lose energy and move closer together, ultimately forming a solid structure. For instance, when water is cooled down, it transitions from its liquid form into ice, which is the solid form of water. This illustrates how freezing results in the conversion of a liquid into a solid, making option D the appropriate answer. Understanding this process helps to clarify various physical changes materials undergo in response to temperature variations.
