Can Reduction in Atmoshperic Carbon Dioxide Cause Famine?
Carbom dioxide, believe it or not, is the life giving force on Earth. Nature depends on the basic chemical reaction of combustion: Carbon plus Oxygen to make Carbon dioxide for giving energy to all forms of life on the planet. It is called respiration. The animals and plants breathe in the oxygen which reacts with the carbon in the starch or sugar in the living cells to form carbon dioxide which we breathe out. The reaction is reversible with the energy of the Sun in photosynthesis which converts the carbon dioxide back into starch which is the food we eat and in the process releases oxygen back into the atmosphere. In this manner the energy of the Sun is obtained by our bodies from food and utilized with the help of oxygen which we breathe in. The entire and sole source of energy of all living beings is nothing else except the Sun.
The total quantity of carbon which is taken out of the atmosphere by photosynthesis in plant growth is about 100 to 120 billion tons of which about 40 to 50 billion tons is returned back as respiration of plants and animals and about 50 to 60 billion from the bacterial activity in decomposing organic materials. The quantity added by burning fossil fuels is only about 5.5 billion tons.
The concentration of carbon dioxide has been gradually increasing over the last few decades at about 1 to 2 ppm per year. It is now at about 380 ppm or about 0.4% of air. It is one of the constituent of what are known as the ‘Green House Gases.’ The other major greenhouse gases are water vapor, ammonia, and nitrous oxide. These gases in the tropopause layer of the atmosphere which is about 30,000 feet above the ground, contribute to global warming through their ability to reduce the radiation from the Earth and thereby result in global warming. The Intergovernmental Panel on Climate Control (IPCC) has determined their effect at 1.6 watts per sq. meter. This is quite small as compared to the total energy of 342 watts per sq. meter from the Sun. The amount of energy reflected back into space is about 30% i.e 77 watts per sq. meter, which is 50 times more than the effect of the greenhouse gases.
Prof. Stephan Salter of the University of Edinburgh has proposed a solution for Global warming which entails creation of low level white clouds over the sea to reflect off Sun’s energy and reduce the amount of heat absorbed from the Sun. This project can economically counter the effect of increased level of carbon dioxide in the air.
Scientists have proved that the rate of growth of plants is dependent on the amount of carbon dioxide in the air. The larger is carbon dioxide, the more is the growth and vice-a-versa. The increased level of carbon dioxide is helpful in growing more food, though it may have a global warming effect. Decrease in the carbon dioxide level may lead to famine. eMaya, the expert on Climate Change and Global warming, has found a solution for the 2 opposing forces for the planet. How to stop Global warming and continue to increase the food production. Read all about it in the ‘eMaya’ book. www.trafford.com/08-0434
General Chemistry 1 problem relating to the gas and pressures law.?
Hi, I need help with this problem and would appreciate if someone can explain to me how it was solved, thank you so much!
A laboratory technician measured the contents of a partially filled 25.0 gallon gasoline drum on a day when the temperature was 18.0 degrees C and atmospheric pressure was 751mmHg, and found that 15.4 gallons of the solvent remained. After tightly sealing the drum, an assistant dropped the drum while carrying it upstairs to the organic laboratory. The drum was dented and its internal volumed was decreased to 20.4 gallons. What is the total pressure inside the drum after the accident? The vapor pressure of gasoline at 18.0 degrees C is 401mmHg. (Hint: At the time the drum was sealed, the pressure inside the drum, which is equal to the sum of the pressures of air and gasoline, was equal to the atmospheric pressure.
Well we know PV =nRT, and we are given the same gas at the same temperature in both situations so we can state that both n and T are constant, as is R. So we are left with P1, V1, P2 and V2 as our variables.
So can can form the equation, P1 x V1 = P2 x V2
P1 = atmospheric pressure = 751mmhg
V1 (of gas) = volume of container – volume of solvent = 25.0 gal – 15.4 gal = 9.6 gal
P2 = ? pressure after the changed in volume
V2 = volume of container (after denting) – volume of solvent (which has not changed) = 20.4gal – 15.4gal = 5.0gal
Plug in our know variables and solve for the unknowns.
(751mmhg) x (9.6gal) = (P2) x (5.0gal)
P2 = 1441.9 gal!
