Copper (II) oxide. [Cu+2]. [O-2] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Copper (II) oxide or cupric oxide is an inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu 2 O or copper (I) oxide (cuprous ...
The density of ice increases slightly with decreasing temperature and has a value of 0.9340 g/cm 3 at −180 °C (93 K). [7]
Copper (I) oxide or cuprous oxide is the inorganic compound with the formula Cu 2 O. It is one of the principal oxides of copper, the other being copper (II) oxide or cupric oxide (CuO).The compound can appear either yellow or red, depending on the size of the particles. [2] Cuprous oxide is found as the mineral cuprite.
In Tl 2 Ba 2 Ca 2 Cu 3 O 10 (Tl-2223), there are three CuO2 layers enclosing Ca layers between each of these. In Tl-based superconductors, T c is found to increase with the increase in CuO 2 layers. However, the value of T c decreases after four CuO 2 layers in TlBa 2 Ca n−1 Cu n O 2n+3, and in the Tl 2 Ba 2 Ca n−1 Cu n O 2n+4 compound, it ...
Phases of ice. Log-lin pressure-temperature phase diagram of water. The Roman numerals correspond to some ice phases listed below. The phases of ice are all possible states of matter for water as a solid. Variations in pressure and temperature give rise to different phases, which have varying properties and molecular geometries.
New York: The International Nickel Company, Inc., 1941: 16. — "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T. Kirke. The Precious Metals, Comprising Gold, Silver and Platinum.

The refractive index of water at 20 °C for visible light is 1.33. [1] The refractive index of normal ice is 1.31 (from List of refractive indices). In general, an index of refraction is a complex number with real and imaginary parts, where the latter indicates the strength of absorption loss at a particular wavelength.
