- water - A liquid made up of molecules of hydrogen and oxygen (HO2). When pure, it is colorless, tasteless, and odorless. It exists in gaseous, liquid, and solid forms; it is liquid at room temperature. It is the liquid of which seas, lakes, and rivers are composed, and which falls as rain. Water is one of the most plentiful and essential of compounds. It is vital to life, participating in virtually every process that occurs in plants and animals. One of its most important properties is its ability to dissolve many other substances. The versatility of water as a solvent is essential to living organisms. The term "water" is typically used to refer to the liquid form of this compound; for the solid or gaseous forms, use "ice" or "water vapor."
- windmills - Refers to a device for tapping the energy of the wind; it typically also refers to the building or structure supporting or housing the device. Characteristically, the device operates by means of a rotating shaft on which sails are mounted or placed at an angle so that the force of wind against them causes rotation, which in turn produced energy. Windmills were traditionally used chiefly in flat districts for operating a mill to grind grain, for pumping water, or for creating electricity. The older and most characteristic European form consists of a conical mill-house with a dome or cap supporting four sails. The more modern American form consists of a disk of sails mounted on a framework of girders, and is used chiefly for pumping or sawing.
