An antifreeze is a chemical additive which lowers the freezing point of a water-based liquid. An antifreeze mixture is used to achieve freezing-point depression for cold environments and also may achieve boiling-point elevation to enable higher liquid temperatures (a colligative agent giving both antifreeze and "anti-boil" when used for both properties.)
Because water has good properties as a coolant, antifreeze is used in internal combustion engines and other heat transfer applications, such as HVAC chillers and solar water heaters. The purpose of antifreeze is to prevent a rigid enclosure from undergoing catastrophic deformation due to expansion when water turns to ice. Commercially, either the additive or the mixture may be referred to as antifreeze. Careful selection of an antifreeze can enable a wide temperature range in which the mixture remains in the liquid phase, which is critical to efficient heat transfer and the proper functioning of heat exchangers.
Most automotive engines are "water"-cooled to remove waste heat, although the "water" is actually antifreeze/water mixture and not plain water. The term engine coolant is widely used in the automotive industry, which covers its primary function of convective heat transfer for internal combustion engines. When used in an automotive context, corrosion inhibitors are added to help protect vehicles' radiators, which often contain a range of electrochemically incompatible metals (aluminum, cast iron, copper, brass, solder, et cetera). Water pump seal lubricant is also added.
I'm working from 9 until 5, I'm working just to stay alive
I don't know what's wrong with me
I have no clue what you are about to do, I have this thing and it's for you
And driving me insane
Last night I talked to you for a while, i was intrigued about your style
You hammered me away
I can't speak clearly I can't think, I thought I was the missing link,
That would put together the chain
I thought I was your missing link
But now I know I was so wrong
I thought I was your missing link
I'm working from 5 until 1, I'm working just to supply my lungs
With all the smoke they need
I have no clue when I am going to die, I hope it's when I'm really high
So I can jump the plane
This plane will take me to your heart someday so then I can be with you
In my own little way
