In simple terms what is polyethylene glycol made of?
Oh, dude, polyethylene glycol is made of ethylene oxide and water. It's like when ethylene oxide and water decide to have a chemical party and polyethylene glycol is the cool result. So yeah, it's basically just ethylene oxide and water hanging out together in a molecular form.
What liquid is used in radiators?
In most vehicles, a mixture of water and antifreeze (ethylene glycol or propylene glycol) is used as the liquid in radiators. This mixture helps to regulate the temperature of the engine and prevent freezing or boiling over.
What Percent of glycol mixed with water will prevent freezing?
Both ethylene and propylene glycol possess many characteristics that make them ideal for use in heat transfer systems where protection from freezing is required. Desirable properties include high boiling points, low freezing points, stability over a wide range of temperatures, and high specific heats and thermal conductivities. Furthermore, used with an appropriate inhibitor, glycols demonstrate a non-corrosivity that may substantially prolong system life. Ethylene glycol based solutions work well in most anti-freeze applications because of their excellent heat transfer efficiency. The low viscosity of ethylene glycol allows systems to operate at lower minimum temperatures and is more energy efficient due to its reduced pumping requirements. The primary drawback to ethylene glycol is that it is listed as a "toxic chemical" under SARA, Title III, Section 313, due to its acute oral toxicity. Inhibited propylene glycol should be used for freeze protection where direct contact with foodstuffs or incidental contact with drinking water may occur. Although propylene glycol is generally recognized as safe (GRAS) by the FDA, it is not intended for human consumption. Hope this helps your question.
Do you check the radiator liquid when the cars on?
NO! That would be dangerous. Cars' coolant systems are pressurized, so if you open the radiator cap while the engine is running, it will spray HOT radiator fluid (water mixed with ethylene glycol, usually) all over you, and sometimes drain the radiator of coolant.
Ethylene glycol test?
DefinitionEthylene glycol is a colorless, odorless, sweet-tasting but poisonous type of alcohol found in many household products. People sometimes drink ethylene glycol mistakenly or on purpose as a substitute for alcohol.A test can be done to check for ethylene glycol in your blood.See also: Ethylene glycol poisoningHow the test is performedBlood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.How to prepare for the testThere is no special preparation needed.How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedThis test is ordered when a doctor thinks someone has been poisoned by ethylene glycol. Drinking ethylene glycol is a medical emergency. Ethylene glycol can damage the brain, lungs, liver, kidneys, and lungs. The poisoning causes disturbances in the body's chemistry, including metabolic acidosis. The disturbances may be severe enough to cause profound shock, organ failure, and death.Normal ValuesThere should be no ethylene glycol present in the blood.What abnormal results meanAbnormal results are a sign of possible poisoning.What the risks areVeins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.Other risks associated with having blood drawn are slight but may include:Excessive bleedingFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)ReferencesPincus MR, Abraham NZ Jr. Toxicology and therapeutic drug monitoring.

What chemicals are used to remove ice from airplanes?
Usually ethylene glycol, the same as the main ingredient in car anti-freeze. Answer Prior to take-off, airplanes are sprayed with a de-icing agent that melts any ice on the airplane and its wings but it will not re-freeze. Once in the air, many airplanes are equipped with electric heaters or devices that blow heated air over the leading edge of the wings and prevents wate from freezing on it.
What effect does ethylene gas have on produce?
ethylene gas is a gas that plants produce to help them grow and age faster sometimes too much ethylene gas can result to over ripening (rotting) to reduce over ripening, put your produce in a cold area such as the fridge because the cold slows down the production of ethylene gas
What do you call the change in the level of the sea over a period of time?
The tide
What must change for air pressure to change?
Your elevation above sea level or the weather passing over you.
What is the boiling point of a antifreeze water mixture?
At atmospheric pressure (that is, with the radiator cap loose or off, and the vehicle at sea level) coolant (50% water and 50% ethylene glycol) boils at 227 degrees F. At 15 psi pressure (the typical pressure at which a radiator cap will vent steam and therefore the typical maximum pressure within a closed cooling system) the same 50/50 mixture will boil at 265 degrees F. (Obviously, with the radiator cap tight it won't matter whether the vehicle is at sea level or not.) Different mixtures of water and ethylene glycol have different boiling points, of course, and different freezing points, too.
What substances can used antifreeze contain?
Used antifreeze can contain a variety of substances, including ethylene glycol or propylene glycol, which are the primary antifreeze agents. Additionally, it may contain contaminants such as heavy metals (like lead or cadmium), silicates, organic acids, and other additives that were originally present in the fluid. Over time, used antifreeze can also accumulate impurities from the engine, such as oil, dirt, and rust particles. Proper disposal and recycling of used antifreeze are crucial due to its toxic nature and potential environmental impact.
What kind of anti-freeze should be used for 1998 Chevy blazer?
You are supposed to use red/orange dex-cool, however there has been a class action lawsuit against GM over this product as it clogs the radiator and causes engine damage when that happens. Standard Green coolant (ethylene Glycol based) will work just as well without the clogging issue
