Incomplete Combustion and its harmful Effects Video Lecture | Science Class 8

in this video you are going to learn
what combustion is the difference
between complete and incomplete
combustion the products of the two types
of combustion and the effects of the
products of combustion combustion is
burning usually in air which is all
around us or oxygen it's an exothermic
reaction which means it gives out he a
fuel stores potential energy that can be
released as heat when we burn the fuel
an example of a fuel is natural gas or
methane this is the fuel we burn to heat
up our food methane like other
hydrocarbon fuels such as petrol can
undergo either complete or incomplete
combustion when methane undergoes
complete combustion that is in a
plentiful supply there it produces
carbon dioxide and water as shown by the
equation ch4 gas plus 2 o2 gas give co2
gas plus 2 h2o gas when methane
undergoes incomplete combustion that's
in a limited supply there it produces
either carbon monoxide and water or
carbon and water is shown by the
equations - ch4 gas plus 3 o2 gas gives
2 Co gas plus 4 h2o gas
ch4 gas plus o2 gas gives C solid plus 2
h2o gas
now the effects of the products of
combustion water vapor as we all know is
harmless carbon dioxide is a greenhouse
gas and contributes to global warming
carbon monoxide however is toxic it's
colorless odorless tasteless and so is
called the silent killer
carbon monoxide is often produced by
faulty gas appliances that's why it's
important to have your gas phase and
boilers regularly serviced on bank
carbon is a particulate and is a
pollutant in the air so to recap
combustion is burning usually an air or
oxygen complete combustion of
hydrocarbons produces carbon dioxide and
water incomplete combustion produces
either carbon monoxide of water or
carbon and water and the products of
combustion have various effects
