Water ice

Water Ice

Ice is water frozen into a solid state. It can appear transparent or opaque bluish-white color, depending on the presence of impurities or air inclusions. The addition of other materials such as soil may further alter its appearance.

Ice appears naturally in forms of snowflakes, hail, icicles, ice spikes and candles, glaciers, pack ice, frost, and polar ice caps. It is an important component of the global climate and plays an important role in the water cycle. Furthermore, ice has numerous cultural applications, from ice cooling of drinks to winter sports to the art of ice sculpting.

The molecules in solid ice may be arranged in numerous different ways, called phases, depending on the temperature and pressure. Typically, ice is the phase known as ice Ih, which is the most abundant of the varying solid phases on Earth's surface The most common phase transition to ice Ih occurs when liquid water is cooled below 0°C (273.15K, 32°F) at standard atmospheric pressure. It can also deposit from vapour with no intervening liquid phase, such as in the formation of frost

 Water and Water Ice an Compacted Snow are Xchange traded commodities. All three commodities are listed under Base Commodities.

Water is traded in 7 trade classes:

 
 * 1) H2O – Pure, This is pure H2O without any other components. Pure H2O must be processed or manufactured and does not occur in nature. Pure water like has industrial, engineering and science uses. The Thala import large quantities. There is always demand for pure H2O with the Klack. Xchange Symbol : H2O – Average Price : 1.50 -3.00 per 1000 ml
 * 2) Water -Drink . This is water that is not deionized and might have some impurities (Minerals). It must adhere to the Union Health Standard for Drink Water. Xchange Symbol: DW. Drink Water is the most common traded commodity and in steady demand. Billions of tons are harvested, shipped and sold all across the Union. Prices vary
 * 3) Water Ice – Frozen Water usually in 1000 kg blocks – Drink Water quality Prices vary
 * 4) Water Ice – Frozen Water, not Drink Water – 1000 Kg blocks , harvested from asteroids, oceans etc. Either used for Drink Water production or Fuel . Average price 7 – 20 credits / ton
 * 5) Waste Water – Organic. Waste Water with Organic contamination of at least 10 kilo solids per 1000 liters. Depending on the type and concentration of the organic contamination this can be quite valuable on Agricultural planets.
 * 6) Heavy Water (Deuterium) – Widely traded
 * 7) Ultra Heavy Water (Tritium oxide) widely traded[1]
