An antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. [ 1 ]
Charles S. L. Baker and his assistant demonstrating a heating/radiator system. Baker worked over the span of decades on his product, attempting several different forms of friction, including rubbing two bricks together mechanically, as well as using various types of metals.
Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol [7]) with the formula (CH 2 OH) 2.It is mainly used for two purposes: as a raw material in the manufacture of polyester fibers and for antifreeze formulations.
It is usually used with additives, like corrosion inhibitors and antifreeze. Antifreeze, a solution of a suitable organic chemical (most often ethylene glycol, diethylene glycol, or propylene glycol) in water, is used when the water-based coolant has to withstand temperatures below 0 °C, or when its boiling point has to be raised.
Antifreeze itself is usually ethylene glycol or propylene glycol (with a small amount of corrosion inhibitor). A typical automotive cooling system comprises: a series of galleries cast into the engine block and cylinder head, surrounding the combustion chambers with circulating liquid to carry away heat;
Chesebrough opened his first factory in 1870. The first known reference to the name Vaseline is in his U.S. patent: "I, Robert Chesebrough, have invented a new and useful product from petroleum which I have named 'Vaseline…'" . The word is believed to come from German Wasser (water) + Ancient Greek: έλαιον (élaion, oil). [5]
A plastic bottle of antifreeze Large plastic bottles of water. A plastic bottle is a bottle constructed from high-density or low density plastic. Plastic bottles are typically used to store liquids such as water, soft drinks, motor oil, cooking oil, medicine, shampoo or milk. They range in sizes, from very small bottles to large carboys.
James Harrison was born at Bonhill, Dunbartonshire, the son of a fisherman. [3] Harrison attended Anderson's University and then the Glasgow Mechanics' Institution, specialising in chemistry. [3]
