Lithium be cut with a knife. When cut, it possesses a silvery-white color that quickly changes to gray as it oxidizes to lithium oxide. While it has one of the lowest melting points among all metals (180 °C), it has the highest melting and boiling points of the alkali metals. Lithium has a very low density (0.534 g/cm), comparable with pine wood. It is the least dense of all elements that are solids at room temperature; the next lightest solid element (potassium, at 0.862 g/cm) is more than 60% denser. Furthermore, apart from helium and hydrogen, it is less dense than
Australian Fair Pay and Conditions Standard Commission who would carry out its agenda. This argument was based partially on the Howard Government's previous opposition to minimum wage increases. The ACTU claimed the five minimum conditions was not sufficiently comprehensive.
