The steam engine needs coal, the coal comes from the coal mine
Coal is mined from coal mines. Liquids like oil can be pumped from wells, but solid chunks of coal cannot.
No, coal is a natural resource.
Coal mining will not last for long because coal is becoming scarce.
it uses brunes coal it burns coal
The surge in demand from electrical utilities, which comprised over 50 percent of coal industry sales, led to two of the most dynamic decades in U.S. coal history in the 1960s and 1970s.
There are 2 different types price elasticity of demand and price elasticity of supply. If you meant to ask is demand for coal price elastic on inelastic, answer is yes, it is price inelastic. The demand for coal, is unlikely to drop much even if the price of it increases, it can be said that it is a 'necessity'. Since the quantity demanded decreases less than proportionate than the increase in price, it is said to be price inelastic.
Coal is not an invention, but rather the natural result of the fossilization of plants from the Carboniferous period.
To increase the capacity of coal trucks you have to complete certain tasks in the seer's village.
The need for coal increased primarily due to the Industrial Revolution, which led to a higher demand for energy sources to power factories and machinery. Coal became a popular choice because it was abundant, cheap, and provided a reliable source of energy for the growing industrial economy.
The rising demand for coal came from many sources
how has demand for coal changed since 1950 the demand for coal has changed drastically scince the 1950's (quite obvious). this is a result of the relisation of the global problems it has had on the environment. the use of coal has also been replaced by more modern forms of energy resoures, such as electricity and gas. during the 1950s coal was used to heat homes, cook food, and even run traind. in modern society scince then we no longer require such a high demand for coal as we do not use it as much to do everyday requirements such as these.
The price of coal varies depending on the level of customer demand. Additionally, the size of the lump of coal will make the price vary.

The demand for coal has changed since 1950 from 200 million to 60 million. This is because the main users are using coal fired power stations. 200 million in what units? Lumps, pounds, hundredweights, ton(ne)s?
Between 1812 and 1860, the growth of cotton and iron industries meant that coal was at a higher demand. New technology was introduced to try to make coal production quicker and more efficient. Cage elevators were introduced to raise coal and miners from the pits, rails and carts were used to transport coal, instead of 'Putters', some mechanical machinery was introduced to cut coal, instead of the 'Hewers' doing it by hand. The invention of the davy safety lamp meant that miners could go deeper into mines, but it also lead to many injuries.
Coal was being used to fuel industrial plants, to make steel, and to power the railroads.
