What are some practical applications of freezing point depression, boiling point elevation, and vapor press?

Answer 1

Have you never seen the roads salted in winter?

See this old answer. And this is a clear exploitation of the melting point depression phenomenon.

And at a more practical level for chemists, boiling point elevation, and freezing point depression phenomena can be used to assess the molecularity of a solute, and sometimes an accurate molecular mass.

And as another example, consider ice-cream. Chemists usually use liquid-nitrogen to make ice-cream. You COULD use water-ice doused with common salt to depress the melting point of water LOWER than #0# #""^@C# while you churn the ice-cream....

Some practical applications of freezing point depression include: lowering the freezing point of water to prevent pipes from bursting in cold weather, enhancing the freezing process in ice cream production, and utilizing antifreeze solutions in car radiators to prevent engine damage.

Boiling point elevation finds applications in cooking, where adding salt to water increases its boiling point, allowing for faster cooking times. In industrial processes, it's used in the purification of substances through distillation.

Vapor pressure is important in various fields, such as controlling humidity levels in climate-controlled environments like greenhouses and museums, as well as in chemical processes like evaporation and drying. Additionally, it's crucial in understanding and predicting the behavior of volatile substances, such as in the design of pressure release valves in industrial settings.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
