why would it not be useful to just use pure ethanil or pure ethylene glycol as aN ANTIFREEZE SINCE THEIR NORMAL FREEZING POINTS are -114.1 degrees celsius and -12 degrees celsius respectively
Ethanol's boiling point is too low for use in automobile engines. Ethylene glycol doesn't have the specific heat capacity that water has.
i put that water neeed to be mix to lower the freezing point temp and not to damage the radiator
Using pure ethanol or pure ethylene glycol as an antifreeze would not be very practical or useful because of the following reasons:
1. Inadequate freezing point protection: While pure ethanol has a freezing point of -114.1 degrees Celsius and pure ethylene glycol has a freezing point of -12 degrees Celsius, they still have relatively high freezing points compared to typical freezing temperatures encountered in many regions. In cold climates, temperatures can drop well below these freezing points. Therefore, using them alone would not provide adequate protection against freezing.
2. Insufficient heat transfer properties: Ethanol and ethylene glycol have lower heat transfer capabilities compared to specialized antifreeze formulations. This means that if used alone, they would not efficiently transfer heat away from the engine, leading to potential overheating issues.
3. Lack of corrosion protection: Antifreeze formulations contain corrosion inhibitors that help protect the engine's cooling system from rust and other types of corrosion. Pure ethanol and ethylene glycol lack these additives, which could result in damage to the cooling system over time.
To create a more effective antifreeze, manufacturers add a combination of chemicals and substances to the base fluid, such as water and corrosion inhibitors. This mixture lowers the freezing point and enhances the overall performance of the coolant, providing both freezing and boiling protection, as well as better heat transfer capabilities.
