Bricks are made with the two most abundant materials on Earth: clay and shale. These two materials are then put in a furnace, called a kiln, and heated to 2,000°F (approximately 1,100°C). By a chemical process (vitrification), the materials fuse together and form bricks.Know More
Concrete bricks, gray bricks similar to clay bricks, are not really bricks, even though people call them such on a regular basis. Concrete bricks are significantly easier to break that clay bricks.
Due to the longevity of clay bricks, some of the American colonial buildings still stand today. A few examples are Virginia's St. Luke's Church (est. 1632), the Boston State House (circa 1713), and Philadelphia's Independence Hall.Learn more about Solutions & Mixtures
Most antifreeze is made from ethylene glycol, but it can contain other chemicals or ingredients, such as propylene glycol, ethanol, methanol and isopropyl alcohol. Some modern types of antifreeze include chemicals that allow them to last twice as long as conventional fluids, while other antifreeze types use propylene glycol as the main ingredient, resulting in a product that is much safer for pets and humans.Full Answer >
White glue is made from water, H2O, and polyvinyl acetate, a polymer of vinyl acetate which has the chemical formula C4H6O2. Polymers are made by chemically linking molecules together in chains of varying lengths, so the formula for polyvinyl acetate is technically (C4H6O2)n, where n can stand for any number.Full Answer >
Jet fuel is made from a mix of hydrocarbon, which are strictly controlled to make sure the freeze point and flash point stay within specific limits. Jet fuel A and A-1, the most common types, are both kerosene-based type fuels and have between eight and 18 carbon atoms per molecule.Full Answer >
Polar liquids are made up of covalently bonded molecules that each have a partial positive charge on one end and a partial negative charge on the other end. They can dissolve solids that are made of polar molecules but cannot combine with a substance made of nonpolar molecules.Full Answer >
