Molten Lead

Melting

Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point. At the melting point, the ordering of ions or molecules in the solid breaks down to a less ordered state, and the solid melts to become a liquid.

Lead

Lead is a chemical element with the symbol Pb and atomic number 82. It is a heavy metal, denser than most common materials. Lead is soft, malleable, and has a relatively low melting point. When freshly cut or melted, it appears shiny silvery with a bluish tint, but tarnishes to dull gray on exposure to air. Lead has the highest atomic number of any stable element, and three of its isotopes are endpoints of major nuclear decay chains of heavier elements.

molten

Adjective

1. Melted, especially due to great heat
2. Made from a melted substance. (Can we add an example for this sense?)

Verb

1. past participle of melt

lead

Noun

1. A heavy, pliable, inelastic metal element, having a bright, bluish color, but easily tarnished; both malleable and ductile, though with little tenacity. It is easily fusible, forms alloys with other metals, and is an ingredient of solder and type metal. Atomic number 82.
2. A plummet or mass of lead attached to a line, used in sounding depth at sea or to estimate velocity in knots.

Verb

1. To cover, fill, or affect with lead.
2. To place leads between the lines of.
