Does china produce Uranium?
Unsure i think it does caus it produces so much energy
Why is coal used so much to produce energy why not try renewable resources?
because were doomed to kill ourselves off honey
Where can you find Australian exports to China?
I produce an Oil skimmer that I have exported to china www.skimmeronline.com Australia exports coal gas, iron, oil, wool and many other materials to China,Coal, aluminium, gold, iron and iron ore, lead, uranium, wool, fruit, timber, sugar, meat, diamonds, pearls and pearl shell, opals, and so on.
How coal used to produce energy?
The coal is set fire to so it heats water which evaporates. This makes a magnetic spin between two coils of wire which generates electricity. :)
Is iron and coal used to make steel?
Yes, they are melted together in a furnace to produce steel.
Why do people take so much coal?
to make money
How much coal is needed to produce 1kw of electricity?
The energy density of coal can also be expressed in kilowatt-hours for some unit of mass, the units that electricity is most commonly sold in, to estimate how much coal is required to power electrical appliances. One kilowatt-hour is 3.6 MJ, so the energy density of coal is 6.67 kW·h/kg. The typical thermodynamic efficiency of coal power plants is about 30%, so of the 6.67 kW·h of energy per kilogram of coal, 30% of that-2.0 kW·h/kg-can successfully be turned into electricity; the rest is waste heat. So coal power plants obtain approximately 2.0 kW·h per kilogram of burned coal. I copied it from wiki page see the same for clear view http://en.wikipedia.org/wiki/Coal regards Raghs
Is coal causing a mojor problen in the world?
A large coal-burning plant annually burns 3 million tons of coal to produce 11 million tons of carbon dioxide. This carbon dioxide is a pollutant and is bad for the environment. So yes, coal can be a major problem-causer.
Why does burning of candle produce flames and burning of coal cannot?
First of all we will have to know that what is a flame made up of,a flame is made at a point where fuel and oxygen combine,so in case of both candle and coal there is a fuel ie.wax in candle and coal is itself a fuel.................but if we just think till this much then even coal should produce flame but it doesn't go like this ,actually we are missing something ie. hydrogen(the main component in every flame producing substance).........if hydrogen is not there flame will not be produced .So wax has hydrogen atoms whereas coal doesn't because coal has been burnt before and hydrogen has been used.................that is why hydrogen containing waxy candle produces flames whereas already burnt coal just gives heat not flames. Hope this helps.
Why has China's population grown so much?
To much children.
Are there other countries using green energy?
The US is the leading polluter in the world so other countries don't worry that much about green energy. China might use green energy though...
What are the two chemical pollutants that are produced by coal fired power stations?
Most coal burned in power stations contains small amounts of the metal mercury. This metal is released and vaporized as the coal burns. Some coal, particularly lower-quality bituminous coal, contains nitrogen compounds. The nitrogen in this coal (and sometimes nitrogen from the air) combine with oxygen to produce various nitrogen oxides, some of which catalyze the formation of ozone in the lower atmosphere. Most modern coal-fired power stations have very efficient combustion, so they produce very little carbon monoxide, but some older plants produce significant (but still small) quantities. Carbon dioxide isn't universally considered a pollutant, but it is the main combustion product of coal. Some coal contains sulfur or sulfur compounds. These can be released by burning to produce sulfur dioxide, which reacts with water in the atmosphere to produce sulfurous and sulfuric acids, which are significant components of acid rain.
