Freezing Point

The freezing point is the temperature at which a liquid turns into a solid when cooled. It is a fundamental concept in the fields of chemistry, physics, and meteorology.

Definition[edit | edit source]

The freezing point of a substance is the temperature at which it changes state from liquid to solid. It is the same temperature as the melting point, but the direction of heat transfer is towards the liquid, not the solid.

Factors Affecting Freezing Point[edit | edit source]

The freezing point of a substance can be affected by several factors, including pressure and the presence of impurities.

Pressure[edit | edit source]

The freezing point of a substance can be lowered by increasing the pressure. This is due to the fact that increased pressure makes it harder for molecules to move and form a solid structure.

Impurities[edit | edit source]

The presence of impurities can also lower the freezing point of a substance. This is known as freezing point depression.

Freezing Point in Everyday Life[edit | edit source]

The freezing point has many practical applications in everyday life. For example, it is used in weather forecasting to predict the likelihood of snow or ice. It is also used in the design of refrigeration systems and in the production of ice cream.
