rated A+ passed
Sulfur Dioxide - ANS ✔A major combustion product of fuels such as coal and oil which may
contain up to 5% sulfur.
Soot - ANS ✔The most visible part of smoke, consisting of particles of unburned carbon and
tars, but also contaminated with other chemicals.
Bronze Age in China and Middle East - ANS ✔- Early coal users
- England developed early coal technologies
Coke - ANS ✔The residue of carbon left after heating up coal, the heat would drive off the sulfur
impurities.
Pyrolysis - ANS ✔the thermal decomposition of organic material at high temperatures in the
absence of oxygen.
Smoke and Particulate matter (PM) - ANS ✔Smoke may also contain very fine matriculates such
as the unburned greasy soot from a candle flame.
Hard Coal, bituminous, black coal - ANS ✔Upper and older end of the range of coal
Brown coal or lignite - ANS ✔The lower or younger coals
Specific Latent heat of vaporization - ANS ✔The energy needed to evaporate 1 kg of nay liquid
, Underground Minning - ANS ✔Includes not only the deep mines reached by vertical shafts, but
others reached by a long sloping tunnel or drift.
Longwall - ANS ✔Two parallel tunnels or roadways are driven and these defiance the parcel of
coal to be worked.
Deep mines - ANS ✔Worked by tunneling. Includes the process of underground mining and long
wall.
Surface Mines - ANS ✔Large, open pits in the earth.
Resources - ANS ✔Quantities of coal (or any other mineral) that are likely to actually exist and
could possibly be extracted at some time in the future.
Reserves - ANS ✔Known with considerable certainty to exist and would be economic to extract
with today's technology and in today's market.
Top coal reserve countries - ANS ✔United States, Russia, China, Australia, India
Hypothetical resources - ANS ✔They are yet to be discovered, but they eventually turn out to
include both reserves and conditional resources.
United States Coal Reserves - ANS ✔Holds a quarter of the worlds reserves.
Four main points of the Industrial Revolution - ANS ✔-1698: Thomas Savery's First Steam Engine
-1709: Abraham Darby's use of coke for smelting iron
-1733: John Kay's invention of the flying shuttle
