Furthermore, What is freezing and example? Freezing is the process when a liquid turns into a solid. Freezing occurs when heat is lost from an object, which causes the molecules to slow down and form tighter bonds. One example of freezing is when water turns into ice. Freezing is the opposite of melting, and two steps away from evaporation.

What are the basic principles of freezing? When a material changes from a solid to a liquid or from a liquid to a gaseous state, the transition involves heat to affect the change; and when the change is not supplied by heat from the outside, the body itself, and anything in contact with it, becomes cooler. This is the concept of freezing mixtures.

Freezing delays spoilage and keeps foods safe by preventing microorganisms from growing and by slowing down the enzyme activity that causes food to spoil. As the water in the food freezes into ice crystals, it becomes unavailable to those microorganisms that need it for growth.

What is process of freezing?

Freezing, also known as solidification, is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point.

How do things freeze?

Freezing. When a liquid is cooled, the average energy of the molecules decreases. At some point, the amount of heat removed is great enough that the attractive forces between molecules draw the molecules close together, and the liquid freezes to a solid.
