Quick Answer: What happened to the boiling point of water when ethylene glycol was added to it?

The addition of ethylene glycol to water raises the boiling point of the engine coolant and reduces the chances of a car’s radiator “boiling over.” The name ethylene glycol communicates much information about the chemical’s structure.

What happens to the boiling point of water when ethylene glycol is added?


Pure water, as you may know, has a boiling point of 212°F (100°C) and a freezing point of 32°F (0°C). However, when you create a 50/50 mixture using water and ethylene glycol, the boiling point rises to 223°F (106°C) and the freezing point lowers to -35°F (-37°C).

Why does ethylene glycol have a high boiling point?

The ethylene glycol can form hydrogen bonds on both ends of the molecule resulting in much stronger intermolecular forces and a higher boiling point.

What is the boiling point for ethylene glycol?

a) Ethylene glycol has no effect on the freezing point of water.

Does ethylene glycol raise boiling point?

Why is ethylene glycol used in antifreeze? It lowers the freezing point of water (and raises the boiling point) and is also miscible with water in all proportions. And that is down to the properties of the molecule, particularly its ability to form hydrogen bonds.

Does ethylene glycol dissociate in water?

Note: ethylene glycol is an organic compound and does NOT break up or dissociate when it dissolves in water.

Why is the boiling point of ethylene glycol much lower than that of glycerol?

Because opposite charges attract each other, this means that ethylene glycol molecules are attracted to each other, making it harder to pull them apart (think of ‘Molecular Velcro’) and this, in turn, makes its boiling point higher than that of hydrocarbons of similar mass. The hydrogen bonding in ethylene glycol.

What is water boiling point?

It seems like one of those basic science facts: Water boils at 212 degrees Fahrenheit (100 degrees Celsius), right? Well, not always. It depends on where you’re doing the boiling. In fact, water will boil at about 202 degrees in Denver, due to the lower air pressure at such high elevations.

Which statement best explains why water has a higher boiling point than ethane?

Which statement best explains why water has a higher boiling point than ethane? Ethane molecules have no hydrogen bonds and need less energy to separate.

Why is ethylene glycol added to water?

Addition of glycol lowers the freezing point of water in the radiator so that the cold winter temperature wouldn’t burst the lines and thus, glycol-water mixture is used as antifreeze in radiators of cars.

When ethylene glycol is added to the water in an automobile radiator?

antifreeze, any substance that lowers the freezing point of water, protecting a system from the ill effects of ice formation. Antifreezes, such as ethylene glycol or propylene glycol, commonly added to water in automobile cooling systems prevent damage to radiators.

Can ethylene glycol be heated?

Ethylene glycol is also commonly used in heating applications that temporarily may not be operated (cold) in surroundings with freezing conditions – such as cars and machines with water cooled engines. Ethylene Glycol is the most common antifreeze fluid for standard heating and cooling applications.
