What is the specific heat capacity of glycol?
For instance, propylene glycol at a 40% concentrated mix with water produces a specific heat of 0.895.
What is the specific heat capacity of antifreeze?
Ethylene glycol has a specific heat of 2.78, and propylene glycol has a specific heat of 2.73. At 50% water and 50% antifreeze, the specific heat of engine coolant is much closer to that of water. This illustrates the necessity of mixing water and antifreeze to make engine coolant!
What is the specific heat when antifreeze is added to water?
Wrenchin’ @ Random. The specific heat capacity of ethylene glycolbased water solutions is less than that of pure water; in a 50 percent solution, ethylene glycol’s specific heat capacity compared with pure water is decreased at least 20 percent at 36 degrees and about 17 percent at 200 degrees.
What is the specific heat of water?
The units of specific heat are usually calories or joules per gram per Celsius degree. For example, the specific heat of water is 1 calorie (or 4.186 joules) per gram per Celsius degree.
Can I mix ethylene glycol and water?
Ethylene glycol is completely miscible with water in all proportions (as the commenters point out). Therefore, once mixed, the glycol will not separate from the water, ever. The only exception is if it gets so cold the mixture starts to freeze.
Why is ethylene glycol a better coolant than water?
Ethylene glycol (antifreeze) is used in the cooling of a car radiator during the winter because it has a much lower freezing point than water. The specific heat of antifreeze (pure or mixed with water) is lower than that of pure water.
Why is ethylene glycol added to the water in a radiator?
Why would ethylene glycol reduce the cooling efficiency of water?
Why would ethylene glycol reduce the cooling efficiency of water? Ethylene glycol has a lower heat capacity than water.
How does ethylene glycol react with water?
Pure ethylene glycol freezes at about −12 °C (10.4 °F) but, when mixed with water, the mixture freezes at a lower temperature. For example, a mixture of 60% ethylene glycol and 40% water freezes at −45 °C (−49 °F). Diethylene glycol behaves similarly.
Is ethylene glycol soluble in water?
TCC’s Ethylene Glycol (MEG) is a toxic, colorless, practically odorless, low-volatility, low-viscosity, hygroscopic liquid. It is completely miscible with water and many organic liquids.
