What is antifreeze. Give an example?

Question

Answer

An antifreeze is an additive which lowers the freezing point of a water-based liquid and increases its boiling point. An antifreeze mixture is used to achieve freezing point depression for cold environments and also achieves boiling-point elevation ('anti-boil') to allow higher coolant temperature. Freezing and boiling points are colligative properties of a solution, which depend on the concentration of the dissolved substance.... Propylene glycol is used as anantifreeze in cars and trucks.... 👍 👍 👍 👍

Answer

It's a enzyme which present in polar fishes to prevent their self to freeze

Answer

Antifreeze is a liquid substance that is used in engines and other machinery to prevent the freezing of liquids and to regulate the temperature of the engine. It is usually a mixture of water and ethylene glycol or propylene glycol.

Types of Antifreeze

There are two main types of antifreeze:

Ethylene Glycol Antifreeze: This type of antifreeze is commonly used in automobiles and other engines. It has a lower freezing point and a higher boiling point than water, which helps to prevent the engine from freezing in cold temperatures and from overheating in hot temperatures. However, it is highly toxic and can be harmful to humans and animals if ingested.

Propylene Glycol Antifreeze: This type of antifreeze is less toxic than ethylene glycol and is commonly used in food processing and other industries where non-toxic substances are required. It has a higher freezing point and a lower boiling point than ethylene glycol, which makes it less effective in extreme temperatures.

Functions of Antifreeze

Antifreeze serves several important functions in engines and other machinery, including:

Preventing Freezing: Antifreeze helps to prevent the engine from freezing in cold temperatures by lowering the freezing point of the liquid in the engine. This helps to ensure that the engine starts and operates smoothly in cold weather.

Regulating Temperature: Antifreeze helps to regulate the temperature of the engine by absorbing heat from the engine and dissipating it through the radiator. This helps to prevent the engine from overheating and causing damage to the engine components.

Preventing Corrosion: Antifreeze contains additives that help to prevent corrosion of the engine components. This helps to extend the life of the engine and prevents the need for expensive repairs.

Example of Antifreeze

An example of antifreeze is the Prestone Extended Life Antifreeze/Coolant. This antifreeze is a mixture of ethylene glycol and water, and contains additives that help to prevent corrosion and provide long-lasting protection for the engine. It is compatible with all types of antifreeze and can be used in all makes and models of vehicles. It has a low silicate formula that provides superior protection against rust and corrosion, and the patented formula helps to prevent leaks and maintain the proper pH balance in the engine.
