Compare with Definitions
Decay
(Biology) To break down into component parts; rot.
Rust
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides (Fe2O3·nH2O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), and is typically associated with the corrosion of refined iron.
Decay
(Physics) To disintegrate in a process of radioactive decay or particle decay.
Rust
Any of various powdery or scaly reddish-brown or reddish-yellow hydrated ferric oxides and hydroxides formed on iron and iron-containing materials by low-temperature oxidation in the presence of water.
Decay
(Electronics) To decrease gradually in magnitude. Used of voltage or current.
