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.
One gram of water takes 4.184 joules of energy to increase its temperature 1 ÂºC. This is the most energy any substance takes to raise its temperature 1 ÂºC. In contrast to taking the most energy to raise its temperature 1 ÂºC, this means that it also takes the longest to cool down. This means that water has the highest heat capacity. It must release 4.184 joules of energy in order to decrease its temperature by just 1 ÂºC. The heat water releases is absorbed by its environment. Knowing the heat capacity of water, it is possible to find how well its environment insulates it.
