Copper deficiency is a rare disease that leads to hematological disorders. It is an essential trace element. It is an essential part of some enzymes (c0-factor) that plays role in cellular respiration. Copper is also an anti-oxidant that scavenges free radicals. In case of cellular respiration copper is responsible for electron transfer of oxygen.
Clean coal technology refers to a gathering of technologies being created in order to reduce the environmental influence of coal energy production and to mitigate global climate change. There are three distinct technological procedures accessible for the aim of capturing carbon as demanded by the clean coal concept:
1. Pre-combustion capture: This includes gasification of a feedstock like coal to generate gas that may be shifted to develop a mixture of carbon dioxide and hydrogen gas, from which the carbon dioxide can be effectively separated and captured, transported, and eventually sequestered.
2. Post-combustion capture: This is the capturing of carbon dioxide from the exhaust gases of combustion methods.
3. Oxy-fuel combustion: The fossil fuels like coal are combusted in a mixture of oxygen and recirculated flue gas, rather than in air that hugely withdraws nitrogen from the flue gas allowing capturing of low-cost and efficient carbon dioxide.
An initial example of a coal-based plant utilizing carbon capturing technology is a Swedish company Vattenfall's Schwarze Pumpe power station situated in Germany.
Answer:
-1.Cold air sinks,has high density,and creates areas of low pressure.
-2.Warm air rises,has low density,and creates areas of high pressure.
-3.Wind is the movement of air from an area of high pressure to an area of low pressure.
-4. The angle of the earth affects the amount of energy an area receives
-5.More sunlight reaches the Earth at the equator
-6.Topics(near the equator) have warm air that rises,creating areas of high pressure.
-7.North and South poles have low air that sinks,creating areas of high pressure.
