The Iron lung was essentially a pressure chamber in which the the pressure could be increased quite a lot over atmospheric pressure as a means of forcing the absorbed coal gas back out. Its other common use was in treating polio, and also divers with the 'bends'.
Diamonds are Carbon; that's it. Coal is mostly Carbon with other elements in it.
Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen. It is of higher quality than lignite coal but of poorer quality than anthracite. Formation is usually the result of high pressure being exerted on lignite.
Coal is abundant and easy to convert into electricity.
Coal is abundant and easy to harvest from the earth to produce electricity relative to nuclear energy. Solar energy is abundant but difficult to harvest compared to coal.
the Providence and Worcester railroad.
President used heavy hand against big buiseness
Mostly it's burned for energy.
Non-renewable. We dig it up out of the ground and we can't make any more of it. Adding more, Coal is found in the depths of earth in form of natural resources, they are formed by processing of the trees and other biological resources
Because the get their coal by rail.
NO? :P I have the same question
Coal mining is a dangerous job in the coal mines, as you see by the devastating explosion just recently. Coal also produces many harmful gases into our atmosphere, so renewable resources are safer for people, animals, the earth, and everything!
1. Overburden O/B 2. Coal / ore 3. Interburden (or parting), I/B 4. Waste Sometimes: Waste = O/B + I/B (look at the context) Waste (O/B + I/B) needs to be removed to get access to coal / ore What Is Stripping Ratio ? a. Measures relative deposit depth Q: How important is depth in surface...
Coal is a hydrocarbon rock formed from geologically trapped deposits of plant matter which were formed over millions of years. The oldest coal deposits are as much as 350 million years old; the youngest are about 15 million years old. Deposits that are younger than that do not have all the physical...
Coal was formed from the remains of plants and animals under high pressure. The sediment on top of the remains provides the pressure to convert peat into coal.
Burning coal releases enormous amounts of carbon dioxide into the air, and is a very large source of global warming as a result. It also releases various other pollutants and contributes to acid rain among other problems. A: Coal is certainly a carbon sink and the burning of coal does put CO2...
Coal that has become diamond.
\nDo the math: Amps x Volts = Watts. Your house is mostly 120V and each circuit is usually 15amps (not counting large appliances).
Well, peat is the kind that comes out of dark unicorns.
200 years with present technology.
Coal is only as homogeneous as the original materials from which it is formed. Many soft coals (lignites) are formed by the burial and compression etc, of forest or shrubland. Thus the coal formed from this will never be homogeneous, and you may find fossilized branches in the material. Many...
Coal is mined by two methods: surface or 'opencast' mining or underground or 'deep' mining. The choice of mining method largely depends on the geology of thecoal deposit. Underground mining currently accounts for a biggershare of world coal production than opencast; although in severalimportant...
They are known as Fossil Fuels and they are non-renewable resources
It forbade the employment of boys under the age of 10 yrs, and banned employment of women of any age in the mines.
coal is black nuclear is purple
Coal is flammable because we use coal for barbecues
No, they should not. In most of the world, it is against the law. Mining- especially coal mining, can be an extremely dangerous job.
Peat becomes coal after being subjected to pressure from overlying sediments for long periods of time. Water and other organic materials are squeezed out of the peat, leaving mostly carbon. The harder the coal, the higher the carbon content. The water is frozen to erosion and evolve
Carbon from decayed vegetation goes through various stages due to heat and compression from peat moss through lignite, bituminous, anthracite, graphite, and eventually diamond. Each has a greater pure carbon content (and less water) than the previous, and therefore greater heating value when used as...
Most Industries are concentrated around coal mines or the following reasons- 1. We know that the major industries are iron and steel industry. 2.The iron and steel industry requires heat to melt the steel to form different shapes. 3.Therefore more heat can be generated by the energy stored in the...
Trains mainly, also trucks
Coal and petroleum consist primarily of carbon. Limestone is the ionic compound CaCO3, known as calcite or calcium carbonate, which contains carbon.
Because its a good power source. And there isn't another viable energy source yet. Hydrogen car? yeah right. Remember the Hindenburg? Electric car? Forget long trips plus electricity is still mainly produced through the burning of fossil fuels so its not a "clean ...
Burning coal is an exothermic reaction as it give heat
it is called surface mining
Basically energy from the sun enables plants to grow by photosynthesis, using chemicals in the soil and atmosphere. Coal is the fossilised remains of ancient plants.
it is formed by being burned which causes heat, which can also be converted into motion energy.
The United States produces about 20% of the world's supply of coal. Montana is the state with the most coal reserves, but Wyoming is the top coal-producing state. Coal generates about half of the electricity used in the United States.
well... coal is very rare and hard to get but it is one of the best natural resources we have.
accumulation of organic matter, compression into peat, compression into coal
From what I've there no such thing as tennis rackets with middle strings made out of coal! I just think people are saying that because they've heard from someone!
Its very expensive to produce coal. If you want to produce it, you have to spend millions on drills and also pay the costs of your company. Who the heck is asking this anyway?
The United States of America is the Leading North American Producer
The colour of the bituminous coal varies from pitch black to grey colour. Sometimes more or less laminated showing layers of bright and dull coals
There were 1493 coal fueled power plants in the United States in 2006. They produce about 50% of the country's electricity.
Coal Is non renewable. You can only use it once, and then it's ash. Renewable means you use it today, like heat stored from the sun, and more heat still there tomorrow to store again. An example involves wood (burned directly) or crops (converted to ethyl or methyl alcohol or biodiesel and then...
because coal is a component that when added to water makes it polluted and increase the chance to have acid rain. By: Kieth S. From: De La Salle University Lives in: Forbes Park Manila
yes because it is made up of various different substances and looks as if to be various different substances due to the crumbling away of freshly mined coal.
Burning is a chemical change, an oxidation.
Coal is considered to be a rock.
Yes, the energy stored in coal came from the sun. Plants using an ingenious process called photosynthesis, use energy from the sun, to take carbon-dioxide from the air, use the carbon and release the oxygen back to the air. After the plant is eaten or dies and is decomposed or burned (the net...
where can i find coal in canada
Coal bearers are kids who have to load their backs with coals
Women and boys under the age of 10
For production of electricity, possibly yes. This won't be for 50 years at least in my opinion, and what the oil sitution will be then is difficult to forecast. There is plenty of coal available. Natural gas may run out. Nuclear fission will expand to some extent, and renewables like wind will also...
No. Anthracite coal is a metamorphic rock.
Answer: Antarctica was in a warmer place before it drifted over the South Pole.
yes. chemical potential energy
No, a person who worked in a coal mine would likely be biased. Also, little data can be extracted from any memoir at all.
No, it is not a fossil. It is a fossil fuel.
dark colors get shine in a very hot iron because dark colors always a good absorber of heat so it absorbs the heat and it reflects as a shine on the fabric.
You get lotsa money for 'em. i had 2k and after selling my ores and coal i ended up wid 44k
It was predicted that our coal resources will last for around 250 years more. I am reluctant to agree with this statement though. Our oil reserves are expected to run out within the next 50 years if technology does not advance enough to give us alternatives. When this happens, our coal consumption...
Diamond is more dense that coal.
Yes, coal is a NONrenewable energy source. It is running out rapdily, which is why we are trying to find alternative renewable ways to create energy, such as recycling and energy turbines.
Steam Enginessteam engineIn the late 1700s what new machines started the industrial revolution
Coal has proved to be very useful for man and his progress in many ways. It has proved as an important source of energy and raw material as well. It is clear from the following examples: The advent of Industrial Revolution was based on the steam energy produced by using coal as a fuel. It is, even...
When you burn something, you are causing an exothermic reaction to occur. When that heat is released from the reaction, is causes more to burn, keeping the exothermic reaction going.
Roosevelt had played a role in resolving the 1902 strike by forming the Anthracite Coal Strike Commission.
Coal can be found easier than oil. However, Green Energy is the future! It is cheaper, cleaner, and healthier. It is a investment in our Children! :)
