Describe the physical properties. 1) Copper. 2) Water. 3) Salts.

Let us describe the physical properties of the following compounds.
1. Copper is a golden-pink ductile metal; in air it quickly becomes covered with an oxide film, which gives it a characteristic intense yellowish-red hue. It has high heat and electrical conductivity.
2. Water – is a transparent liquid that has no color (with a small layer thickness), odor and taste. In the solid state it is called ice (ice crystals can form snow or frost), and in the gaseous state it is called water vapor.
3. Salt – are crystalline substances with an ionic crystal lattice.
