Give reason for the following:
(a) Air holes of the gas burners have to be adjusted when heated vessels get blackened by the flame.
(b) Use of synthetic detergents causes pollution problems.
Give reason for the following:
(a) Air holes of the gas burners have to be adjusted when heated vessels get blackened by the flame.
(b) Use of synthetic detergents causes pollution problems.
(a) In case of the vessel in which cooking is done, when it gets blackened from outside, this means that combustion is incomplete. As a result, the carbon particles in the form of soot get deposited and the vessel becomes black from outside. In order to check this, oxygen or air supply must be increased. This can be done only by adjusting the air holes of the gas burner.
(b) The pollution problem caused by the synthetic detergents is due to their non-biodegradable nature. These are actually long chain organic compounds which do not break or decompose in water. Naturally, this will result in pollution problems. Some of the detergents are even of toxic nature and will make water unfit for drinking.
