Soil Profile. There are different types of soil, each with its own set of characteristics. Dig down deep into any soil, and youâll see that it is made of layers, or horizons (O, A, E, B, C, R). Put the horizons together, and they form a soil profile. Like a biography, each profile tells a story about the life of a soil. Most soils have three major horizons (A, B, C) and some have an organic horizon (O).
At a pilot facility in Singapore, Siemens has cut the energy needed to desalinate seawater by more than 50 percent. The plant processes 50 cubic meters of water per day, consuming only 1.5 kilowatt-hours of electricity per cubic meter.
The water's temperature continues to rise as the energy is added until the temperature is 100 C. At that point, you continue to add energy but the temperature no longer rises. Instead, the water boils. The energy input now is going into moving water molecules from the liquid to the gas phase. The water molecules have attractive forces between them which constitute a low energy. You have to do work (add energy) on the molecules to pull them apart and make them a gas. The opposite occurs in solidification of water.
