The book also states that ice-nine reverses the normal hierarchy in which living organisms use water as a resource, becoming the "successor of organic life on planet Earth". [ 7 ] Leonard Susskind 's The Cosmic Landscape calls Cat's Cradle and its use of ice-nine a "cautionary tale about madness and instability in a world full of nuclear ...
Ferromagnetism: A state of matter with spontaneous magnetization. Antiferromagnetism: A state of matter in which the neighboring spin are antiparallel with each other, and there is no net magnetization. Ferrimagnetism: A state in which local moments partially cancel. Altermagnetism: A state with zero net magnetization and spin-split electronic ...
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
The term phase is sometimes used as a synonym for state of matter, but it is possible for a single compound to form different phases that are in the same state of matter. For example, ice is the solid state of water, but there are multiple phases of ice with different crystal structures, which are formed at different pressures and temperatures.
For example, the triple point at 251 K (−22 °C) and 210 MPa (2070 atm) corresponds to the conditions for the coexistence of ice Ih (ordinary ice), ice III and liquid water, all at equilibrium. There are also triple points for the coexistence of three solid phases, for example ice II , ice V and ice VI at 218 K (−55 °C) and 620 MPa (6120 atm).
In 1935, Linus Pauling used the ice rules to calculate the residual entropy (zero temperature entropy) of ice I h. [3] For this (and other) reasons the rules are sometimes mis-attributed and referred to as "Pauling's ice rules" (not to be confused with Pauling's rules for ionic crystals). A nice figure of the resulting structure can be found in ...

Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water covers about 71% of the Earth's surface, with seas and oceans making up most of the water volume (about 96.5%). [23]
